Back panel padding provides amazing comfort for a frameless pack
Frameless design requires careful loading
Lots of exterior mesh complicates brushy routes
This is a carefully designed and solidly built pack that performs at a very high level for its flexible structure and light weight. The AS-2 is also an organizational wonder—for those users who need everything in its right place, this pack delivers.
Comfort/Adjustability One of the most adjustable bags we tested, the AS-2 also received high marks for ventilation. On the other hand, carry-comfort suffered if the pack wasn’t loaded just-so; and some users felt that the back panel padding was tough to get used to.
Stability For such a flexible pack, though, it carries even awkward loads extremely well. Load lifters were not as effective as we’ve come to expect from packs of this size.
Capacity Given the great versatility of the AS-2 and its variety of external carry features, its ability to carry larger loads was limited by its frameless design and lower volume.
Organization/Access With two-way zip panel access, extra pockets everywhere, and accessible water bottle carriers, the AS-2 sets a new standard for daypack organization.
Features Nearly every feature on this pack was both ergonomic and functional. And while some extras (the helmet-hammock, for one) were brilliant, others (eg, the many hipbelt pockets) could be difficult to work around.
Value A great value for fast-paced users who desire detailed organization in a lightweight package.
