Reviews - Outdoor Research Drycomp Vertex Sack

Thomas Kachadurian - 2008-08-21

Very light, great pack
This is one of the very few light truly waterproof packs. The weight is listed as 17.7 oz, but it feels like nothing. When the shipping package came I thought it was empty. It's extremely comfortable to wear full or empty. I am using it as a dry bag to get my gear to and from my boat every day. I have a few complaints about the design. 1. The "Hydration sleeve" is a waste of space. It would be much more valuable to have a few zippered pockets for loose items. 2. There are just too many straps. While the multi-purpose waist belt/compression straps sound like a good idea in practice they just get snagged on things. They should be attached with fastex at both ends so they can be removed, or put the compression straps in a channel or sleeve to keep them covered. This might be my own personal issue since I have this general complaint about most pack made these days. 3. The "one-hand" pulls on the water bottle pocket drawcords are hard to use even with two hands. All three of these are small issues and do not take away from the great useability of this pack. I wish they made a small waterproof daypack in the same material.
