Familiarity: I've used it several times
For backcountry snowboarding I like my packs light and small, so I don't feel awkward when I try to spin or play around on the way down the mountain. This guy is great in that respect, as it somehow doesn't way too much more than my regular pack and thanks to the helmet carry pocket it fits all my gear nicely.
One thing I would mention is that it doesn't have a good place for lashing tour poles. Not a problem for me since I keep my Black Diamond Compactor poles inside, but if you already have telescoping poles you might want to make sure they fit in the Float 22.
