The new JetForce Pro is still battery-powered for easy travel and avoids refilling compressed air canisters, but it's now 1-2 pounds lighter and built around a modular design. Black Diamond essentially makes a base unit with four different booster packs that are surprisingly inexpensive, adding to this model's overall value. We feel that the JetForce Pro offers tremendous value despite the high upfront costs.
We tested the 35L version of this pack and found it to have solid overall utility, although it wasn't quite our favorite. Our testing team liked its oversized snow safety tools pocket, which easily fits larger shovels and probes and can still squeeze skins in, too. You have to open two different zippers (one on each axis) to open the snow safety tools pocket but in reality, this only takes an extra second or two and certainly isn't a deal-breaker.
We liked the top zippered compartment, which basically doubles as the brain/lid of the pack. Most airbag packs that feature a clamshell-style opening have no brain/lid compartment and every tester who used this pack took full advantage of it. The small trade-off is that there is no dedicated goggle pocket — most users will want to put their goggles in a case in the brain/lid compartment.
Another change from the previous JetForce to the new JetForce Pro relates to airbag storage. The old model used a series of plastic clips that would unexpectedly open regularly if your pack was on the fuller side. This wasn't a danger, but it was annoying (and silly) skiing down the slope with a deflated airbag flopping around. The newer model uses the more common break-away "burst" zipper (which can still open unexpectedly when the pack is full, but this happened less often than on the previous generation).
The main compartment on this pack is spacious, but narrower than most. The stowed airbag parallels the zippered opening, making it harder to dig for items if you don't want to lay the pack on the ground and fully unzip it. However, the zippered access point wraps all the way around the pack, so if you know where your stuff is and don't pack it too full, you can access nearly any point of the pack reasonably well. We offset this inconvenience some because the lid pocket/compartment was so big, and this is where we kept most smaller commonly wanted items.
This model can only carry skis diagonally. It features a fixed lower loop on the back of the pack, which sounds like a bummer, but we used it with skis ranging from 88mm-118mm underfoot, and all of them fit. The ski carry tends to lean the skis further forward (tips hanging over your shoulders/head) than other models, though — a design we noticed worsened if the back was only partly full. We think ski carry systems are pretty low down on a pack's priority list, but if you often find yourself carrying your skis for some reason — especially if you don't always expect your pack to be full — then this is one of our least favorites.
Black Diamond was the first company on the market to use a battery-powered fan for bag inflation, and now they've moved on to the second generation of their proprietary JetForce airbag system (or third, if you count their licenses of the Alpride supercapacitor technology, which was our favorite system). The JetForce Pro 35 uses BD's proprietary JetForce technology. After the Alpride E1 system, the JetForce system is a close runner-up for our review team's favorite airbag technology.
The latest version of the JetForce, the JetForce Pro, is smaller, lighter, and has been repositioned to make packing your bag easier. It utilizes a rechargeable battery to power a fan to inflate a single 200L airbag, the largest such volume bag currently available.
As for the 200L bag, is bigger better? Studies haven't proven either way, but inverse segregation (the process in which airbag packs function) works by letting smaller particles shift downwards, moving the largest particles to the surface (think of a bag of chips). Therefore, a larger airbag has few disadvantages other than being heavier and bulkier in your pack when not deployed.
Unlike compressed air canisters, which have a finite amount of air to fill a given airbag, a battery just needs to have enough power. Black Diamond opted for a larger airbag because their battery-powered fan no longer had a cap on how much air they had to work with; according to BD, they did it "because they could".
Once the trigger is pulled, the fan inflates the bag in roughly three seconds, on par with compressed air or gas. Once inflated, it keeps pulsing air for three minutes so that if the bag gets torn, it can still be effective. Black Diamond says that the bag is still 100% effective even with a 6-inch tear in the bag. After three minutes, the fan reverses, deflating the airbag in hopes that the now-deflated bag will create a bigger air pocket for a trapped wearer and hopefully increase their survival time. Black Diamond claims their rechargeable lithium-ion battery will support four deployments per charge, enabling the user to repack the airbag in the event of a close call, a misfire, or what we feel is most important, which is to inspire people to use it in a moments notice, without hesitation.
In reality, it's unlikely that you'll need multiple pulls; we think the biggest advantage of having multiple inflations per charge is that users will be less likely to hesitate before pulling the trigger. A study by the University of British Columbia found that slightly over 20% of people who die in avalanches while wearing airbags don't pull the trigger (this was split between people who hesitated until it was too late and people who were caught but still had their trigger stowed).
Because a computerized system is more complex than a compressed air system, the JetForce Pro has self-checking diagnostics. This system briefly fires the fan in reverse to ensure your airbag pack is ready to go. Once all of this is complete, a green light is displayed for visual confirmation. This green light continues to flash throughout the day, letting the wearer know that everything is operating as it should be. Lastly, the new JetForce Pro is Bluetooth compatible, and you can update software and check firmware by linking your pack to the BD app on your phone.
Black Diamond's JetForce Pro can be purchased in one of four sizes, then you can purchase three other Booster size options to change your pack's volume. These Boosters are swapped out by zipping them onto your base pack. There is a 10L volume, which is generally too small for touring and is most useful for side-country, heli, or cat skiing, and two 25L options, one geared toward skiers and one toward snowboarders. We found these 25L volumes nice for most simple day tours, but they aren't spacious. Finally, the 35L option is great for guides and other avalanche professionals and also nice for big day tours and overnight hut trips.
The JetForce Pro uses a battery and not compressed air; this means there is no refilling involved. Recharging can be done at home, at a hut, or in a hotel. This is obviously far easier than performing a cartridge swap or finding somewhere to refill a compressed air canister. In addition, there are no flight restrictions on checking the battery of the JetForce packs. Easy travel is a big benefit of this pack.
We think one of the biggest improvements Black Diamond has made is in weight savings. Similar-sized packs are around one to two full pounds lighter than previous models. Weight can range from 6.25 lbs (for the 10L size) up to around 6.75 lbs (for the 35L size we tested). This puts Black Diamond's line of packs around average among the competition. In previous years, they were by far the heaviest.
One of the main notable features of this pack is the fact that it's modular. The additional (and quite affordable) "Booster" packs you can purchase change the carrying capacity of the JetForce Pro to meet your individual needs, preventing you from having to purchase a separate and expensive pack for different applications. We also appreciate the oversized snow safety tools pocket and clip-on leg strap.
We found this model pleasant when carrying heavier loads, but it's a little bulkier and stiffer than average. Compared to packs of similar volume, this pack was a touch below average for downhill performance. This is mostly because this pack only has two small compression straps, and if its main compartment isn't full, the user will end up with a floppier-feeling ride. This is worsened because this is one of the wider packs from waist-belt to tail, so the load is further away from the back panel than most models.
We found this pack to provide plenty of support for heavier loads, and its wide, articulated shoulder straps wrapped around us nicely. The waist-belt looks pretty minimal but actually proved quite adequate in real-world use. Two things worth noting are that some smaller framed users didn't like this model's wider shoulder straps, but most medium and taller users found they spread the weight out nicely. Secondly, everyone noted that this pack is on the stiffer side, which can be nice for a bigger pack, but those looking at this model for its smaller volumes might be happier with something a little lower profile.
This is a great choice for those who plan to fly with their airbag pack frequently since its airbag system is airline-approved. We also recommend this pack for those who will appreciate having a quiver of the different booster packs/volumes with one base unit. This unit is also great for its ability to be deployed four times on one charge, significantly decreasing the chances you'll hesitate before pulling the trigger in an emergency.
