I was in the bike shop on Floyd Road in Smyrna, by the SC trail yesterday, and they had a backpack with hydration marked down from $99.50 to $57.00, so, I looked it over and bought it. It is made by a company called Platapus. The model is the Typhoon.
It is a combo unit. I was told that they did not sell very well, so they are marked down and sold on clearance. I believe that I got the last one. I ordered two extra bags for it. I wanted it so that I could take my camera, and maybe a rain poncho, or whatever, on longer rides. I also wanted a place to put my firearm. (Yes I have a license to carry one) I will be getting a camel back type water only, meaning much smaller, pack later.
Does anybody else use one of these type of systems? I put some Gatorade in it to try it out on the way back home. It doesn't seem too bad, but there is no real way to keep the liquids cool. The directions say to put ice cubes in it. Fine with me I guess.
