Good Pack - Could use little improvement
Working into my third season with this pack. Weight is great, fit is near perfect. Breathable back pad is awesome.
Only bad: Water bottle holders don't work too well (not accessible easily), but I use them to store tent poles and fishing rod etc. and they work fine for that.
Removable upper compartment could (and will) make a great side hike daypack with a little modification.
Water pouch takes some room from the rest of the pack and isn't the greatest hydration system. Solve this by bringing a steripen and less water.
