This is where I fit. I sweat so much it really makes no difference. Since I ride hard I want the bike to "feel right" underneath me. I don't like the feel of a bunch of weight strapped to the bike when I get out of the saddle or am hammering. If I absolutely need to I'll do a rack and be loaded down. Most days its a backpack with a change of clothes or a few things, extra tubes, tools and lights etc.
