I owned the Float 18 and this pack is a big improvement. There is now enough space in the pack for me to take it on day tours. I can fit a light down jacket, mittens, 32L Nalgene, goggles, skins, food, and a med kit. There is even a little extra room to spare. The biggest downfall of the pack is the ski carry strap. It is simply too large, and with no adjuster, your skis end up hitting rocks and your boots while hiking. I cut my strap in half, did a little sewing, added a buckle and now have an adjustable strap like the Float 30 did. Also, I still wish there was another external pocket (besides the hip belt), so I don't have to go in the main compartment, but oh well. The helmet carrier works perfectly. I can't wait til next year, when the "pack only" option will be available" and I can swap the system to the 32 pack if needed. Actually I'd suggest that BCA sell a 36 or 40, since the 32 is pretty damn close to the 22.
