Wes Wyliewrote a review of DAKINE Altitude ABS 40L Backpack - 2460cu in on November 19, 2012
Familiarity: I've used it several times
Highly recommend over ABS 40 liter, more pockets and room. ABS shovel storage not practical if you are using your shovel alot, but will handle a large shovel like the Chugach Pro which will not fit into the Dakine so you have to settle for a smaller shovel. Also the Dakine does not have a dedicated hydration bag holder when you use it with the Vario. The one that comes with the Dakine is attached to the harness system and cannot be transferred....big mistake. All things said, slightly smaller shovel, no hydration system, still a more functional pack than the ABS 40 liter.
