Comments about Nathan HPL #063 AR Hydration Pack - 100 fl. oz. - Special Buy:
I rarely had to open up the large compartment to get stuff, most of it was accessible on front straps and waist belt. Tons of stuff fits into the outside back "pocket." I liked the "no zipper" main opening. I used it on a 7 day day hiking trip to Yosemite.
