ABS Packs
Just got one. Vario 15L cover. With shovel/handle, probe, saw..... mounted on the outside it has more room left over inside then my BD Outlaw. All loaded up I can get all avy gear, 2 way radio, camp stove, skins, spare socks and jacket, and a few other odds and sods in it. Quite happy with it so far. And with the Vario base unit that I got, I can always buy a 30 or 50L bag and it just zips onto the base unit. Got it from Rockey Mountain Extreme in Calgary.
A little steep at $1200 but well worth it in the long run.
