Digital airbag packs are costly, however they’re a lot simpler to journey with than compressed air programs, plus they permit for take a look at firing and a number of deployments off a single cost. BCA’s Float E2 35 (MSRP: $1299.95) makes use of Alpride’s E2 airbag system and whereas not new to the BCA line this season, it’s among the finest digital airbags in the marketplace. It sits between the extra compact and agile Float E2 25, which we’ve beforehand reviewed right here, and the Float E2 45, which is able to communicate extra to guides, hut journey heavyweights, and in a single day aficionados.
On this two-season evaluate of BCA’s Float E2 35 (testing started in early spring, 2023), we’ll contact on each the backpack itself and the Alpride E2 airbag system. Between the comparatively light-weight, low-volume, and travel-friendly airbag componentry and the well-designed, rugged pack, the Float 35 is good for splitboarders and backcountry skiers who’re robust on their gear and passport alike and want extra quantity for longer excursions and larger targets.
BCA E2 system’s guts.
Fast Bio: Who The Hell Are You?
Earlier than I dive into the evaluate, let me begin by saying that is my first article for Wild Snow (longtime listener, first-time caller). Since a reviewer’s private preferences dictate how related their perspective is to you, right here’s a short bio (be at liberty to skip this in case you may care much less). In the event you’re nonetheless right here, I’m a lifelong snowboarder who began splitboarding in Colorado within the winter of 2010/2011, and shortly thereafter stumbled right into a profession in out of doors journalism. After bouncing across the Rockies and Wasatch for the final fifteen years, I now stay in Tahoe, the place I cut up my time between touring and chairlift-accessed shredding. I’m additionally an excessive gear nerd, direct splitboard testing for each Exterior Journal and Backcountry Journal, and journey extensively (perhaps excessively?) in pursuit of powder.

All that to say, like many frequent flyers, I’ve all the time gravitated towards electrical airbags. Over the past decade, I’ve had the privilege of testing a handful of airbags, and watching as yr after yr the know-how has gotten higher, lighter, and fewer cumbersome. The present state of digital airbag affairs–as evidenced by the BCA Float E2 35 I applaud under–is considerably extra enticing than they had been 5 years in the past. Issues nonetheless aren’t excellent, thoughts you, however we’re getting a hell of quite a bit nearer.
A Transient Be aware on The Panorama of Digital Airbags:
Digital airbags have been round since 2014, when Black Diamond launched the JetForce system a decade again—these packs had been revolutionary however heavy, amidst different points. Be at liberty to peruse Wild Snow archives for extra of a historical past lesson. As I discussed above, there’s been important evolution during the last ten years, and there are two primary digital airbag programs we suggest as we speak: the Alpride E2 system (a latest improve to Alpride’s E1 system, which we first examined in 2018) and the LiTRIC system, each of that are powered by electromechanical supercapacitors (extra on these under). You’ll discover the E2 on baggage from BCA in addition to Deuter, Scott, and Osprey. The LiTRIC system, alternatively, you’ll discover on Ortovox and Arc’Teryx baggage. The programs are pretty comparable, with the LiTRIC system being a contact lighter (100g), however we dive into the professionals and cons of each under.
Alpride E2 System: Low-Quantity And Journey-Pleasant
Wild Snow’s already coated the Alpride E2 supercapacitor system fairly completely on this article, the second piece of a two-part evaluate on BCA’s Float E2 25 (half one right here) when it first got here out in 2022. For essentially the most half, I received’t regurgitate this largely technical info–-which is properly value studying in case you wish to nerd out—however as an alternative focus extra on my hands-on expertise with the system within the subject and comparisons to each a competitor and predecessor.
Evaluating the E2 System to the E1 Predecessor
We first examined Alpride’s E1 system on the game-changing Scott Backcountry Patrol AP30 again in 2018 when the digital system first launched. We received our fingers on the two.0 replace with BCA Float E2 25 in 2022, when the replace hit the market. As is typical for a product to earn a “2.0” badge, the E2 is considerably up to date, improved, and slimmed down. Alpride claims the E2 system is 140g lighter than the E1 system and 40% smaller, regardless of including 12 liters to the expanded airbag quantity. Whereas I didn’t take away and weigh E1 and E2 programs (Wild Snow beforehand reported a measured distinction of 130g), I positively seen the distinction in quantity.
The BCA E1 system in Osprey’s older Soelden pack and the E2 within the BCA Float 35
Right here, I included a photograph of an older Osprey Soelden Professional 32, which makes use of an Alpride E1 System (the present Soelden providing from Osprey has been upgraded to the E2 system). You’ll be able to see an apparent distinction in dimension. After raiding the fridge for dairy merchandise for comparability, the E2 is nearer to the 16-ounce tub of cottage cheese, whereas the E1 is nearer to the 32-ounce yogurt. Scientific evaluation, I do know. However the huge distinction I seen is that after I pack up the E1 system, I’ve to essentially take into consideration the place to fit cumbersome gear like Nalgenes, crampons, et cetera, because the compressor dominates the majority of the primary space for storing. With the E2 system (granted, the BCA has an additional three liters of quantity), the compressor is way more compact, much less obtrusive, and extra of an afterthought whereas packing.
Chobani for scale.
One other improve of the E2 system over the E1 is a small LCD display screen on the compressor that gives charging information. That is an addition, not a substitute, to straightforward LED indicator flashing lights that are additionally seen from the surface of the pack via a mesh patch. Personally, I appreciated the addition of the display screen as a result of my mind understands bars signifying battery life significantly better than Morse Code flashing, colourful lights. The exterior lights additionally solely let you know what the general cost degree is, whereas the LCD display screen offers you extra information, telling you the cost degree of each the supercapacitors themselves (the electromechanical components that fireside off the airbag upon deployment) in addition to the 2 AA batteries that high off the supercapacitors for as much as three months when you’ve charged through USB. Talking of, the E2 costs off quicker USB-C as an alternative of the E1’s micro-USB.
Yet another replace: extra easy deflation. The airbag auto-deflates after three minutes, however in case you’re simply training or wish to minimize deflation time down, there’s a deflation knob that’s accessible via a zipper built-in into the mesh panel on the surface of the pack. Translation: you don’t have to empty or unzip your primary compartment to deflate.
All instructed, you don’t want a PhD in supercapacitors (which I positively don’t have on my gear room wall) to glean that the Alpride E2 is a serious improve from the E1. Nonetheless, how does the system stack up towards the competitors? Particularly, the award-winning LiTRIC system discovered on Ortovox and Arc’Teryx airbags.

Evaluating the Alpride E2 to its Greatest Competitor: Ortovox and Arc’Teryx’s LiTRIC System
I’m not going to dive tremendous deep right here, as I’d like to avoid wasting lung capability to wax on the backpack itself, which, in my view, is a serious draw for anybody contemplating this airbag. Moreover, as I discussed, I’m no supercapacitor brainiac. Nonetheless, it’s value rapidly evaluating the Alpride E2 system to its greatest competitor: the LiTRIC.
The LiTRIC system can also be primarily based on supercapacitors, and it’s a contact lighter than the E2 (1100g in comparison with the E2’s 1190g, which does embrace the double AA batteries). I’ve been testing the Ortovox Tour 40 since this previous spring, and I favored the push-button type on-off swap of the LiTRIC system extra, because the E2’s pull-and-twist mechanism is slightly annoying, however it is a minor gripe. Each programs appear to take up an analogous quantity of pack quantity, though the LiTRIC airbag is extra condensed and sits larger than the E2 system within the pack, which I additionally dug. The positioning appears to depart slightly extra fully unencumbered actual property for packing gear, whereas the airbag pocket on the BCA pack has noticeably much less depth however takes up extra floor space of the again paneling. One other minor distinction.
However, the BCA pack’s E2 set off will be zipped into the shoulder strap–a design ingredient you received’t discover within the lighter, less-featured Ortovox Tour 40. As an airtime-addicted albeit not notably gifted snowboarder who likes to leap off cliffs and infrequently eats great quantities of shit, I actually respect with the ability to zip away the deal with. You can even swap the set off via the opposite shoulder strap on the BCA, or use one facet for a hydration system or a BCA Hyperlink Radio. Nonetheless, the LiTRIC does permit you to twist and lock the deal with so that you don’t unintentionally deploy the airbag, and that characteristic is well-designed, simple to make use of, and far appreciated.
The largest distinction between these two programs is arguably the way in which that the supercapacitors are recharged. The LiTRIC makes use of a built-in lithium-ion battery, whereas the Alpride E2 makes use of two AA batteries. For more information on this, Wild Snow contributor Jason Albert dissected the ins and outs of the lithium-ion battery and the LiTRIC system right here.
To me, one of many primary advantages of going with the E2 system is which you could high up the supercapacitors after deployment with contemporary AA batteries. In the event you’re on an extended expedition and received’t have entry to an outlet for weeks on finish, you may convey alongside additional batteries and be assured in recharging after a deployment. Right here’s a be aware from BCA on utilizing alkaline versus lithium-ion AA batteries, and what which means for deployments within the subject:
AA BATTERIES FOR ADDITIONAL DEPLOYMENTS
Along with the supercapacitor storage, you may set up two AA batteries to permit for extra deployments within the subject. The batteries additionally assist preserve the supercapacitors at full cost when not in use.
AA alkaline batteries permit for one extra deployment and is able to conserving the system charged for as much as three months of regular use. AA lithium batteries permit for 3 extra deployments and is able to conserving the system charged for as much as 5 months of regular use.
Vice versa, a good thing about the LiTRIC system is that you simply don’t want to convey alongside batteries, because the lithium-ion battery recharges the supercapacitors after deployment. I examined the Ortovox bag on a three-week journey that concerned a 10-day expedition in Norway’s Arctic Circle. Whereas I by no means needed to deploy the pack on that journey, I had zero issues leaving it on all the time within the form of gnarly, sub-zero temperatures which are imagined to be troublesome for lithium-ion batteries (as evidenced by a contact of frostnip on two toes).
There are execs and cons to each of those programs, in addition to delicate variations in weight, however they’re each stable. In comparison with the digital airbags of yesteryear, we’re actually in a renaissance of avalanche security (which hopefully continues on and on), and I reckon anybody who’s upgrading to both the LiTRIC or E2 system from a earlier technology (or a compressed air airbag) goes to be stoked. My recommendation? Moderately than focusing solely on the system itself, I like to recommend utilizing pack quantity, weight, options, and backpack particulars to select your subsequent pack. I’ll focus extra on the Ortovox Tour 40 in one other article, however for now, let’s dive into why I dig this BCA choice.
My recommendation? Moderately than focusing solely on the system itself, I like to recommend utilizing pack quantity, weight, options, and backpack particulars to select your subsequent pack.
Extra Causes I Love The BCA Float E2 35
Sturdiness
From day one, I had a speculation this pack could be extraordinarily sturdy, and that speculation proved appropriate. The material is hard–a PU-coated Nylon 420D armor that handles the whole lot from moist slush and snagging branches to spilled electrolyte drinks and overhead bin wrestling matches. I’ve put most likely 30 days in on this pack on the sector, together with a weeklong hut journey in Sweden, a two-week street journey within the Alps, and a visit to Hokkaido. After important journey, the one put on and tear I seen is a few beauty fading of lettering and a miniscule tear alongside a bit of piping on the “Aspect Stash” zipper (extra on that under).
Journey-Pleasant Construct
I’ve flown with this BCA pack to a number of nations and throughout the western United States. As I discussed above, the sturdiness is such that you simply don’t have to child it in transit. Extra importantly, TSA (most likely) received’t provide you with a tough time because it’s an digital airbag. I had one problem throughout umpteen legs of journey in Washington DC. TSA did search the pack, nevertheless it was moderately fast, I prevented a strip search, they usually quickly despatched me on my approach.
Nicely-Designed Pockets and Options
Considered one of my greatest pet peeves with avy packs is when producers ditch sure pockets to maintain weight down. I perceive the why–I simply personally like to have a microfiber-lined goggle stash pocket, a hip belt pocket for snacks and chapstick and scraper… you get the image.
The Float E2 35 doesn’t skimp. The primary compartment is tremendous spacious–-I discovered it stable for stashing bigger objects like emergency puffies, a mirrorless digital camera, sleeping bag liner, et cetera. The exterior zipper is curved, a characteristic I used to be initially involved about durability-wise however proved rad within the subject. The zipper rapidly filets the primary compartment open like a tuna within the Tokyo fish market, offering entry to each nook and cranny.
There’s additionally an elective zippered divider simply beneath the compressor, which helps separate dry duds from moist skins and water bottles, or sharp crampons, so on and so forth. This zone is accessed rapidly through the Aspect Stash zip, which will be externally operated whereas the pack is on–a plus on time-sensitive missions. One other inside organizer pocket is positioned on the airbag storage pocket, which incorporates an built-in key clip.
Past the primary compartment, there’s an simply accessed avy pocket demarcated by an orange zip, with separate sleeves for shovel and probe. I examined it with a number of shovels, the beefiest being the BCA Dozer 2T. The blade suits, however it’s a contact comfortable when absolutely loaded. There’s additionally a small zippered pocket contained in the avy pocket, which I used for gear I’d hardly ever use, like my binding restore package.
As I discussed already, I like a microfiber-lined goggle pocket, and BCA’s is well accessed. The hip belt pocket (singular, sigh) was spacious sufficient for my slimmer iPhone, a number of mini Snickers bars and gummies, chapstick, and my trusty scraper.
General Capability & Exterior Carry Methods
Quantity, in fact, is a private recreation. In the event you’re fortunate sufficient to have a number of avalanche packs in several volumes, good for you. However for many backcountry customers, I say 35 liters is a candy spot for a Swiss Military Knife, do-everything pack. It’s larger than I want on most excursions–32 is a lot for me, normally–however BCA outfitted the pack with A-frame ski carry straps that double as compression straps, and you’ll compress the pack down a contact if it’s not absolutely loaded. (Exterior carry attachments additionally embrace a stashable helmet hammock, vertical board carry, diagonal ski carry, and ice axe attachments–all helpful and appreciated necessities.) Nonetheless, the 35-liter pack has sufficient hauling potential for larger days while you’re packing sharps, colder days while you want severe layers, and even fast-and-light overnights or hut journeys.
The one time I really maxed out the pack was on a weeklong hut journey in Sweden (we pulled in group meals through a sled, and didn’t want sleeping baggage). I used to be in a position to match a spare set of socks, base layers, sleeping bag liner, two Nalgenes, toiletries, and down hut booties, in addition to crampons, an ice axe, harness, and a Petzl RAD system. It was maxed out, but the padded shoulder straps and agency foam again panel ensured the weighty pack remained manageable.

Strong Experience High quality
I used to be very impressed by the downhill experience high quality. I had no downside hucking myself off cliffs and pillows or driving on the fringe of my capacity in freeride terrain. The padded straps, hip belt harness and the stiffness of the again panel, plus the compression straps for cinchability, permit you to ship it when it’s go time. Strong–no notes right here.
A Few Minor Critiques
The draw back of the Float E2 35’s sturdiness, as you may most likely guess, is weight. Whereas the Alpride E2 system is pretty aggressive, the pack itself just isn’t the lightest choice in the marketplace. BCA claims the burden is 6.1 kilos, whereas my low cost baggage scale appeared to have the medium/massive pack be nearer to five.5 kilos, however positively sub-6. The Ortovox Tour 40, compared, has a claimed weight of 5.42 kilos, and my scale has it hovering proper round 5 kilos, if not a hair beneath (though it’s lacking some options like a hip pocket–extra on that in a soon-to-come evaluate).
In the event you’re grumbling in regards to the lack of exact information, pricey gram counter, my apologies. I’m not a quick and light-weight man–I’m a splitboarder who’s extra involved with downhill efficiency than uphill pace–and I don’t personal a drug seller scale. My regular problem is overpacking for worldwide journey, therefore the baggage scale. Perhaps if Wild Snow retains re-upping on critiques, I’ll lastly fulfill, as Rick Ross as soon as waxed, my triple-beam desires.
Drug trafficking jokes apart, I’d additionally like to have two hip belt pockets, however the correct hip has a loop as an alternative. Alas. Additionally, whereas there are two ice axe loops, the pack solely comes with one velcro strap. You may get round this–I typically rode with each an ice axe and a whippet–nevertheless it’s value noting.
Whereas I didn’t discover any points with the chest strap as Albert did in his Float E2 25 evaluate, I had the left facet of the hip belt loosen a few occasions whereas touring. This wasn’t frequent, nevertheless it was minorly inconvenient and required re-cinching.
Lastly, I’m fairly skinny (5’9”, 155 kilos, 30-inch waist initially of touring season, 29-inch waist in spring) and wanted the hip belt cinched virtually all the way in which down on the uphill for consolation and on the descent for rideability. In the event you’re a few inches skinnier than me, it’s possible you’ll be slicing it shut on a medium/massive pack.

The Verdict: The BCA Float E2 35 Is Prepared To Ship For Seasons To Come
A litany of execs overwhelm a number of minor cons (which we see in nearly each airbag) right here. All instructed, the BCA Float E2 35 is a completely featured and extremely sturdy avalanche airbag that makes use of one of many two main digital airbag programs in the marketplace. In the event you’re counting grams, it’s not the lightest digital airbag pack on the uphill, nevertheless it’s constructed to final, well designed, user-friendly, and ultra-organizable. The 35-liter capability, mixed with compression straps, makes it a candy choose in case you’re in search of one airbag that works each on common excursions and larger days alike. The battery rechargeable supercapacitor is a good choose for expedition use. Most significantly to this powder-hungry reviewer, it presents skiers and riders wonderful downhill really feel, match, efficiency, and safety.
