Familiarity: I've used it once or twice and have initial impressions
Love the pack. Shovel holder and size is perfect. Just skied 6 days at Snowbird and Jackson Hole, however flying out of Salt Lake they will NOT allow you to check the canister and handle, even though it clearly states on the box that it meets IATA standards. I had to wait for fed ex to open and even then it has to ship as a hazardous good. Quite expensize and a pain to travel with at this point.
