I've taken it on several bc trips this year, and as long as you pack thoughtfully it can hold everything you need, and the ski down is great.
I carry a spot locator, small first aid kit, down sweater (if you want extra warmth, needs to be down otherwise I don't think it will all fit), goggles, big warm gloves, nalgene and a hogie. Plus of course shovel (short grizzly) and probe. One drawback is that if you use a camelback in the sleeve I find it very hard to pack (easiest with the shovel flush against the back, though a detachable shovel might change things), so just bring a nalgene instead. Another issue of course is size, I need to swap out my big gloves for skins on the way down.
The ski strap system is fine for short carries, and fits any size ski. I have dynafit manaslu, not sure if I'd want to lug pontoons on this system
Minimal outside straps, but I can thread my helmet chin strap through the two small outside loops, and the have a cord running through the haul loop to store my jacket if its a warm start.
Fit is great, super snug and slim profile, great for the skiing down; just takes some thought on packing and organizing to gt it right.
Overall, just big enough for day long BC trips, and perfect for semi-off-piste at a resort. Five stars, for what it is supposed to be.
