UPDATE SPRING 2015: We just found out to our dismay that Bentgate can not ship replacement gas cartridges to certain cities. Very very disappointing. Contact Bentgate to find out more, and don’t depend on quickly shipping cartridges to a ski destination.

Two ends of the Alpride spectrum. Air Mtn 40 to left is Scott's largest airbag backpack. It’s slightly reworked for 2015-2016 but nothing earth shattering. If you need a larger airbag backpack this one helps keep things on the lighter side by weighing 2.9 kilos, 6.4 pounds (all our weight specs include cartridges). Air Mtn AP 20 to right is a trim Euro style pack with enough room for minimalist touring gear, verified with calibrated scale at 2.3 kilos (without bottle holder or helmet net). It’s also slightly improved for 2015-2016 with a better trigger stowage compartment and a few other minor changes. While 20 liters of baggage capacity isn’t going to work for some styles of ski touring, it’s plenty of room for a shovel, snacks and a layer or two. Swapping Scott’s Alpride airbag system between packs is fairly trivial, so you could own one of these for your quick and fast days, then swap the guts into perhaps Scott’s 30 or 22 liter models if you need to carry more gear.
Overall, the Alpride airbag system from Scott continues its impressive design evolution. I enjoyed spending time with system developer Marc-Antoine Schaer during the recent Scott media gathering in Davos, Switzerland. Marc is an interesting guy, a super-fit ski tourer, pilot, wind surfer and all around alpinist. He’s also one of the nicer people you’ll meet in the mountains. It’s the pilot part that comes into play with Marc’s Alpride airbag work. Attention to detail is superb, all parts are engineered and tested to “commercial aviation standards,” meaning even the smallest changes are assumed to have major consequences and need a huge amount of thought and testing before they go to retail.

Scott AP22 interior. For .4 kilo (14 ounces) more than AP20 you get two more liters of capacity. That doesn’t seem like a good trade, but does show the AP20 is built with lighter fabric and less extra doo-daddery. We suspect the AP20 when stripped down will yield a very nice volume-weight ratio. Razor at the ready. But seriously, Scott should make a bigger version of the AP20 with perhaps even fewer interior fabric layers.

The aluminum chest strap buckle on 2014-2015 Alpride airbag backpacks took some getting used to. For 2015-2016 they’ve switched to a strong but more easily operated plastic buckle, the waist belt buckle remains as aluminum. In testing for standards compliance these packs are tortured to high loads. Knowing that, I’m not worried about the buckles and prefer a chest buckle I can operate without asking for help. The other change in this area of the packs is the chest strap height adjustment is hidden within the shoulder strap compartments, and the trigger handle compartment is a bit larger and easier to use.
At this time the Alpride designs are in three known (to me) iterations. Due to the complexity of these systems and the TUV testing to CE standards, each iteration takes about 3 years to make it to retail. So at any given time the airbag of the future is actually out there in use and being tested — only you won’t see it for quite some time.

Marc carries around his demo plumbing in a foam hardcase like he’s transporting jewelry or a top secret weapon system.

Alpride motor is precision machined; multiple tubes and ports have to be carefully created. It’s called a motor because it creates suction that pulls in ambient air from the outside to mix with the cartridge sourced gas.
The first 2013-2014 release of the Alpride has an aluminum colored inflator motor (the metallic chunk that the cartridges attach to). If you run across that version it has no functional problems but later versions are much nicer in many ways. The current retail release in stores now, with inflator system known as “Bertol 1” (named after the Bertol Hut in Switzerland) has the orange anodized motor and is 200 grams lighter than the first release.
For 2015-2016, Bertol 1 will get a few minor inline changes.
– Lettering on the aluminum motor will be white in black.
– Brighter color on the internal part that indicates if the inflator is armed or not
– Improved cable housing, more flexible and with better end clips.
The 2015-2016 backpacks get a few changes: Where possible, the panel loading zipper is relocated nearer the outside of the pack, so you don’t feel like you’re loading upside down Tupperware. Trigger handle stowage is easier, sternum buckles are plastic and easier to operate, re-activation key has a nice little pouch next to the cylinders (though weight fanatics will want to leave it at home.)
Bertol 2 plumbing is what you’ll get if you purchase an Alpride in 2017-2018 and will be functionally identical to Bertol 1. Beyond that I’m sworn to secrecy, though knowing Marc I suspect it might be a few grams lighter still.

NEW for 2015-2016 Scott Air Free AP12 Pro avalanche airbag backpack is a bit small for full-on backcountry skiing, but it’ll work well for quick tours, freeride, and that sort of thing. Fairly lightweight at 2.3 kilos due to the small amount of fabric, and removable back protector can trim weight but should probably remain in the pack as you need to keep the plumbing from damaging you if you land on your back. This backpack is built more along the lines of a “wearable” garment with its wide shoulder strap system and two sternum straps. Obviously intended for highly athletic forms of skiing such as aggressive freeride. Women’s torso length available as well. I always question the need to make packs heavier so they handle better, but in the case of doing backflips perhaps doing so is necessary. Or, at least while riding the tram you should be looking as if you do backflips as casually as a French freerider lighting up a cigarette.

Summary: While we’re fans of several other airbag brands as well, we like the Euro style influence visible in the Alpride packs, and we especially like the simple refill system — though each fill will set you back around $35.00. For details on how the Alpride packs function using CO2 and argon gas cylinders, please see our introductory post from last winter. We’ve also experimented with modifying these packs, which is instructive though we don’t recommend playing around with the inflation system unless you do a lot of your own testing. Note that the Alpride system is already licensed to Millet and Ferrino, and both companies are installing the plumbing in several backpacks. Be sure to check out Alpride.com, quite a nice focused product website.
