Best for light day hikes, peak bags, or just something that can be used in everyday life.


  • Had a collapsible framesheet built in, even when removing the one included with the pack.
  • Able to handle up to fifteen pounds comfortably. Carries laptop and school materials better than Osprey Manta 25.
  • No complaints.


  • Webbing hip belt, but the angular distribution of weight puts it all on the small of the back which is quite comfortable if needing shoulder relief.

Used this when hitting a couple of slot canyons in the UT South Desert, carried it around as a daypack when needed and was well worth the extra pound or so.

Bottle pockets fit about anything you can toss in it, and has enough room to carry extra layers, lunch, the survival essentials, and then some. Rode extremely comfortable for a small pack on a big guy. 52" chest, 6 ft. and 240lb.

Adaptable, has loops over the back shove-it pocket that allow for putting on shock cord, running carabiners with gear onto it. Wouldn't recommend pushing over 25 lb. but shoulder straps are the perfect balance between thinness and width to spread loads comfortably.

Took the foam framesheet out, but the pack by itself has enough rigidity built in that you dont really need this. The framesheet is nice though if needing a seat, backrest, or even a really thin 1/2 sleeping pad during the summer but that is kinda pushing it.

Didn't get the five because haven't exactly encountered the perfect pack, and who has. Weight is excellent, and is now a constant companion in nearly all variants for my kit.
