    Too Small

      This is too small for what it is advertised. there is no way this pack can hold 18L. a case of bottled water is 30 - .5 liters which would be 15 liters of water. There is no way this pack could even hold the case of water if you poured it in.

      Atom (really) means Small

      • Familiarity: I've used it once or twice and have initial impressions

      Good pack. Solid construction. Functional and comfortable. Downside is this bad boy is small and I have 'things' I like to carry.

      Simply Good

      • Familiarity: I've put it through the wringer

      Great daypack. Simple no frills and bombproof. I've carried it for 80 miles and it looks like its fresh off the rack. 18L is plenty big for Socal hiking and everyday use.

      Unanswered Question

      How is this for day hiking? The back zip pouch seems like it would fit a hydration bag fine, which is usually less annoying than a water bottle on the side anyway.
