Mt Whitney Zone Forums Gear Heads Day Pack

Bob this may be exactly what you are looking for. REI has the
GoLite VO24 Day Pack on sale, normally $90, but now $69.93.
Well padded in hips, weight is 1 # 6 oz and volume is 1500
cubic inches. Both the VO24 and Peak Pack below are hydration compatible.

It was recommended to me a year ago by someone on the Whitney
Portal Store Message Board and I bought one at reg. price, but
have not regretted it. Check it out on REI.com and put
GoLite Day Packs in the search area. GoLite also makes a
slightly bigger Day Pack: Peak Pack, 2200 cu inches, 1# 11 oz and it costs $125 at REI.
