Pros Durable, comfortable, optimized for ski mountaineeringComfortable, affordable, durable, fully featuredSimple, light, comfortable, highly modularSimple, good weight to volume ratio, durableLightweight, simple, excellent pack for steep, technical terrain
Cons Heavier, novel front access zipper can be difficult to useNot as lightweight as some packsDifficult to overstuff for the approach, some finicky featuresCan't remove the foam suspension pad, not best for heavy loads, requires thoughtful packingLess durable, less versatile, no side straps
Bottom Line The durability and feature set of the Ortovox Peak Light 32 make it particularly well suited to ski mountaineeringThis is a comfortable and versatile pack that climbs well on all alpine terrainHighly versatile and impressively lightweight, the Ascensionist is well designed for technical climbsThis pack is light, durable, simple, and comfortable, making it more versatile than most ultralight packs we’ve usedWhat the Blitz lacks in versatility it makes up for in performance in steep, technical alpine terrain
