- was slim enough to manage on a chair lift;
- had two compartments - one for the shovel/probe/skins/avie science gear, another compartment for personal gear;
- a small pocket on the hip for glide wax, skin wax, scraper and diamond file;
- cross-draw straps for skis - faster than an a-frame system, and it leaves the compartments accessible.
Advertised to be 1300 cubic inches / 20 Liters, this pack is the ideal day tour size. Providing you don't need technical gear or a lot of extra layers. Typically mine held 1L of water or thermos, lunch, a down jacket, and a notebook in addition to my avie rescue and science gear. It handled that much fine.
The Drift has two compartments - a main and a sleightly smaller "shovel". The main compartment had a "camelback" and two "pole" sleeves. The shovel compartment had drain grommets, a small "wallet & keys" zippered pocket, and again two long pole sleeves.
Ideally, I was hoping that my shovel, probe, shovel handle, saw, beacon, and avie science stuff could live in the shovel compartment. That way when I'm getting ready for a day out all I needed to do was open the main compartment to pack a layer, lunch, and liquids. It would also mean that everything that can get snowy/wet would stay away from everything I want to stay dry - wet skins would fit in the shovel compartment too.
The shovel compartment on the Drift wasn't tall enough to fit my shovel handle, probe, or saw - the saw barely fit in the main compartment. So my ideas about packing tended to be a bit haphazard.

keeping the shovel handle in the main compartment with the probe
The Drift had three zippered pockets: on the left hip, the left outside, and inside the shovel compartment. These were great - I was able to keep a bit of skin wax, glide wax, a scraper and a diamond file in the hip pocket; sunscreen and headlamp in the side pocket; and keys and wallet in the shovel compartment pocket. I only wished that the shovel compartment pocket was big enough for an 5.5"x8.5" Rite-In-The-Rain notebook, and that another zippered pocket existed in the main compartment for keys and wallet.

but hate to go digging for when you do
One thing the Drift gets an 5-star review for is the number of straps: just enough. There are two straps for a snowboard, two straps for compression, and two straps for a cross-drawed pair of skis. The upper snowboard strap conveniently hides in a pair of pockets - a feature I didn't discover until today!

I've taken this pack out on 13 days this season, from mid-winter to yesterday's spring couloir tour. Gregrory recomends this pack for loads up to 40 lbs / 18 Kg: I'd have to recomend it for a little less than that. Yesterday I hiked for a couple of hours with skis, poles, and boots loaded onto it in addition to the normal kit, and while I handled the load I could certainly see others who may find the hip belt too thin, and loading the shoulders over-much. While the pack features an insulated hydration sleeve in the left shoulder strap, I never had the chance to try it out. And yesterday we took ice axes for our tour, but I didn't have anywhere to stow mine.
