Light and affordable
I have been really happy with my Float 32. It has quite a bit of storage space in the main compartment and has a dedicated avalanche tool compartment. It has enough storage space to carry a lot of gear for a full day. My favorite features are the helmet carry and the lined goggle pocket. I considered the Mammut and the ABS packs as well but in terms of price and weight you really can't beat the Float 32. Also, the cylinder is really easy to refill because it is filled with compressed air. You can get it filled at paintball or scuba shops for about 10 bucks.
