Porter Water Bottle Holder - Nalgene®

Elastic Drawstring Doesnt Work + Doesnt Fit Snug

Drawstring might as well not be there, and as other reviewers have commented it doesn't fit snug on its own, needs a small carabiner to secure it.

Works with my Prism

Purchased this to have an attachment for easy water access with my Prism pack. Managed to jam it into a gap in the waist belt webbing, and works pretty solid. Great for easy access on the flats. Wish it was a bit easier to get on and off, but it will do the trick.

Water Bottle Holder

It's lightweight and keeps the bottle in place. This should come standard with the pack and not as an accessory
