I started wearing an underarmor shirt under my long sleeve shirt and carrying my frame day pack with my camelbak bladder in it so I don't have to stop to drink water, worked out quite well
LOL...yeah, my wife calls me an UA whore. I'm all compression geared out. The stuff works though, I love it. <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
Jared, sounds like you need just a bladder carry system, instead of a full pack.
