The K2 15 Liter Float Pack is the smaller version of the 30 Liter Float Pack, but boasts all the same features and abilities of its big brother. K2 has partnered with BCA to create a line of avalanche float packs that compare well with the highest end offerings from other brands. Both the 15 and 30 liter packs were designed to carry all the necessary backcountry safety gear for guides, backcountry enthusiasts, and anyone who doesn't want to leave any equipment at home. Stay safe with K2 Float bags!

Compressed Gas Cylinder Not Included.


  • A well-thought-out design gives the K2 Float 15 plenty of space to fit the gear you'd need on a day tour. A thick zipper with three sliders (each with big pull-loops) accesses the main pocket, where the compressed air cylinder attaches to the airbag. Inside the main compartment, which is big enough to stash a shell, puffy, gloves, and lunch, K2 built a smaller pocket to keep the air cylinder separated from the rest of your gear. Two mesh pockets hold smaller accessories like keys and a notebook. The pack also comes with a removable lunch bag (large enough for a PB&J and an apple) that attaches to two large strips of Velcro inside the main compartment.

    A separate front pocket was built specifically with easy access to carry your shovel, probe, and skins. A small hole in the bottom of that pocket lets moisture run out, and also doubles as ice-axe storage.

    The K2 Float 15 lets you carry skis diagonally or vertically. It also features a fleece-lined goggle pocket, a mesh strap to stow your helmet, a pocket on the waist belt, and an ergonomic EVA back panel. The fit was long, took up the length of my back, from the top of my hips to my shoulders, and felt snug. It distributed weight evenly, and was comfortable to move and ski in.

    Initially, I had wanted the 30-liter version, but after skiing with the 15 liter, I realized I didn't need the bigger pack. The 15-liter gave me all the space I needed and kept the weight down. And if the worst ever happened, the handle to deploy the airbag is right where I need it—right next to my left shoulder.

There is so much that goes into what size board you need. The biggest misconception is that you buy a board based on if it comes to your chin, nose, eyebrows… something like that. Remember that when you are standing on your board, it has no idea how tall you are! As you initiate turns by bending the board, your body weight is a key factor as well as what kind of riding, where you are riding, foot size and lots of other factors that can influence what is right and what is no right. When you buy a board from us we will steer you in the right direction… remember we Guarantee It.
