I have a clip that keeps the bite valve for my hydration pack on my shoulder. I like my fanny pack hydration pack.

People will make fun of you for whatever they want to. I don't let it bother me. Seriously, maybe 1/4 of the people on rides here wear them. The only crowd likely to say anything is the super-competitive lycra-clad racing bunch. And even then - maybe not.

Seriously - I'd worry about the poop. A bunch of people got sick on a ride here a few years ago. It had rained, and the poop from livestock trucks sprayed up on their bottles. ICK!
