Backcountry Access Float 42 Review

A well-designed larger volume airbag pack that excels for patrollers, guides, or other extended missions - it just doesn't fit the majority of short users

Our Verdict

The BCA Float 42 Tech is the newest model in BCA's line of airbag packs. This model is slightly more feature rich compared to BCA's other float packs the Float 22 and 32. This contender is designed with guides, ski patrollers, or multi-day tours in mind. It will easily work for most hut-to-hut trips or is the perfect sized pack for backcountry professionals, and it has the snow safety gear pocket to prove it. Our testers loved the overall design and features of this pack, with the only small downside, being it was tougher than other airbags we tested to pack tightly for trips where you needed all of the 42L of space. The price is $700 and does not include the canister, which is an additional $200. This contender is still less than others in our review and gives up little in the way of performance.

Our Analysis and Test Results

Product Update

Since we last tested it, the Float 42 has undergone some significant changes. Most notably, the Float 1.0 inflation engine has been replaced by the 2.0 version. Check out the side by side comparison of the new Float 42 (left) and the version we tested (right), and keep reading for an outline of the changes.

Here's a summary of key differences between the new Float 42 and the original we tested:
  • Inflation Engine — According to BCA the new Float 2.0 cylinder is about 30% smaller and 15% lighter than the 1.0 and it stores within the airbag compartment, thus freeing up space within the pack. It is important to note, however, that the 2.0 system is not compatible with bags built for the 1.0 system and vice versa.
  • Material — With hopes of increasing durability and waterproofing qualities, the new version is constructed of a 210 denier mini ripstop nylon with a PU coating for the main fabric, a 420 denier nylon with a PU coating on high wear areas, and a 200 denier polyester lining.
  • Compression straps — New side compression straps were added, which allow the wearer to carry skis in an A-frame configuration! While BCA does not recommend carrying skis this way in avalanche terrain, it adds more overall versatility to the bag.
  • Stitching — BCA added some reinforced stitching to this bag.
  • Waist belt — This new waist belt is adjustable, allowing the user to move the belt up or down by three inches, thus accommodating different sized torsos.
  • Snowboard Carry — New straps were added that allow for a vertical snowboard carry.
  • Back Access — The back panel unzips to allow easy access to main compartment items that may be difficult to get to from the front zipper.
  • Shorter — The overall height of the pack has been decreased to fit a wider range of bodies.

The rest of this review reflects the original version.

Hands-On Review

Float 42 Tech avalanche airbag pack was a strong contender for our top pick for big days and multi-day tours but it was only barely edged out by the Black Diamond Saga 40 primarily because the Saga was straight-up easier to pack tightly. We still think this is a fantastic pack with several superior features including a much bigger and more user friendly snow safety gear pocket.

Refilling Options

The Float 42 Tech like the rest of the BCA line, features compressed air canisters in all of their Float packs. Refills of compressed air are easier to come by than compressed nitrogen, and cheaper, too.

Travel Considerations

You are allowed fly on commercial airlines with an unfilled compressed air canister as long as it's in your checked bags. A good extra measure to take is to keep the box that your canister originally came in and when you travel, pack it in the box to clearly define what your canister is and help make sure TSA doesn't confiscate it.

Our Review team LOVED the snow safety gear pocket featured on the Float 42. It could easily pack a 300cm probe, larger than average shovel, snow saw and still have room for skins. We also liked that there was a very small fast-tec buckle featured on the zipper to help make sure it stays shut in the event of an avalanche so it is less likely the wearer will loose their snow safety gear.

Backcountry Utility

The BCA Float 42 Tech is a feature rich airbag pack with backcountry travelers and climbers in mind. One of our favorite "packs" in the review, our testers loved its large snow safety gear pocket that it was bigger than the Float 32, Black Diamond Saga 40 or Arc'teryx Voltair 30. It had the ability to stow above average sized shovels, saws, and probes.

The clam-shell style design opening for the main compartment of the BCA Float 42. This design was okay to pack tightly but did make finding smaller items that had worked their way to the bottom relatively easy considering the volume of this pack.

The main compartment was easy to access and fairly easy to cram stuff tightly into, but maybe not quite as easy as the BD Saga 40. Like many packs of this volume, items deep inside the pack would occasionally be harder to find; however, due to the Float 42 Tech's clam-shell style opening, it was easier than the Black Diamond Saga 40. Overall we found this pack very functional for its volume and it only just barely missed out on our Top Pick award for the best pack for multi-day trips because the Saga was just plain easier to jam items into but we liked the pockets and snow safety gear area of this pack better than the Saga 40.

The BCA Float 42 Tech features a quick and easy diagonal ski carry system that was our straight-up favorite of the review. Not only was it very functional and secure but it was also extremely easy and quick. WE also liked that this pack has the option to A-frame style carry your skis as well.

Carrying Skis or a Snowboard

The BCA Float 42 Tech is one of the few airbag packs that can carry skis both diagonally or A-frame. The Float 42 Tech's diagonal carry setup is slick and extremely easy to use, working even with the fattest skis or splitboards out there (We have used it with 127cm underfoot skis). The A-frame is an option for lower elevation approaches; it's cool for sure, but remember carrying your skis in an A-frame may interfere with your airbag's deployment. For non-splitboarding snowboarders, an additional snowboard carrying system is available from BCA for $35. In the end we found BCA's diagonal ski carry system to be the extremely functional, secure,and the easiest to use overall.

We really liked all the little extra features on the Float 42: like the oversized fleece lined goggle pocket, dual daisy chains for lashing crampons or other items, large twin zippered waist belt pockets (that are the biggest such pockets in the review) and it is made with a very burly material. One of our favorite additional features was the permanently attached and easily stow-able helmet carrier that very securely held our helmet in place and tucked away nicely. The Float 42 also has places to hang a hydration bladder and the shoulder straps facilitate running a hydration tube through (offering some insulation) as well as the ability to carry two ice axes. In terms of overall performance, the Arc'teryx Voltair 30 once again took home a perfect 10 out of 10, along with the Float 32, and the BCA Float 42, tested here.

The Float Tech 42, like the Float 32 runs a little longer and fits medium to taller framed users better. Its frame does run a little taller than its little cousin the BCA Float 22 and isn't a good option for folks with shorter torsos. It does run around the same fit as the Float 32. As far as comfort, the Float 42 Tech handles loads well and its suspension can mostly much handle whatever you can possibly fit inside it. With that said, it is around the same comfort level when fully loaded as the BCA Float 32 or Mammut Ride Removable 3.0, and our testing indicated that the BD Saga 40 and Mammut Light Removable 3.0 were more comfortable when carrying a heavy load, taking home a 9 out of 10 compared to the Float 42's 8 out of 10.

Downhill Performance

The Float 42 Tech moves relatively well with your body, especially considering its larger than average volume. Scoring the lowest score for downhill performance (a 6 out of 10), this pack is dependent upon how much space you'll actually need. The BCA Float 32 scored an 8 out of 10, offering a higher level of performance on the down, while the Black Diamond Saga 40 scored an 8 out of 10 and offered a similar size volume and more comfort when heading down the mountain. While no contender scored a perfect 10, the Arc'teryx Voltair 30 and Black Diamond Halo 28 were close behind, bringing home a 9 out of 10 for this metric.


The Float 42 Tech weighs in at 7 pounds 3 ounces, which is somewhat heavier than average among airbag packs (in our fleet) overall. Compared to other airbag packs of similar volume, like the Black Diamond Saga 40 JetForce, the Float 42 Tech is lighter, with the Saga 40 weighing 7 pounds 11 ounces. The Mammut Light Removable 3.0 takes the cake in this category, scoring a 10 out of 10, weighing only five pounds six ounces and costing $580.

Best Applications

The BCA Float 42 Tech is best for big day tours in complex terrain or as an overnight pack for extended adventures, or hut-to-hut trips. It is also an ideal size for backcountry guides, ski patrollers, or other avalanche professionals who will appreciate its extra space, many of its additional features, and large, easily accessible snow safety gear pocket.

Value and Cost Breakdown

The Float 42 Tech costs $700 for the pack and an additional $200 for the canister, bringing your total cost to $900. Compare that to the other 40L+ packs like the Black Diamond Saga 40 Jet Force ($1150), the Float 42 Tech is considerably less than many other packs in its size range. Even the slightly smaller Mammut Pro Protection, which is $780 + $200 for a cartridge helps you realize the Float 42 Tech is an awesome deal.

The Bottom Line

The BCA Float 42 is best for folks looking for a larger volume airbag pack, for overnight tours, hut-to-hut adventures, or because you simply need a little extra space. It is a far better deal than many other packs in its volume range and sacrifices very little in the way of performance. Our testers loved the layout and design of the Float 42 and enjoyed most of its pack features better than the Black Diamond Saga 40 JetForce, with the Saga 40's primary advantages being it's easier to travel with, has optional multiple deployments, and is just easier to pack stuff tightly in when it comes to maxing out its volume. We would note that if you are looking for an airbag pack essentially exclusively for day touring use (unless you are a backcountry guide or avalanche professional), we would recommend getting a slightly smaller pack, only because the Float 42 Tech is big and somewhat sacrifices some on the descent - compared to smaller packs.
