for awhile i was using an eagle creek travel thing from the outdoor store. had room for brevet card, id, my old phone, pen, cash, credit card, etc. what i liked about it is that it would ride in my h-bar bag or in my carradice – and when i stopped the first thing i did was take it out and sling it around my neck. had all my essentials for convenience store runs and controls right with me…

compressing that down into a jersey pocket sized item is a nice idea. adding a vapor or water barrier would be key. i have one of those little wallets that is supposed to be ‘sweat proof’ from an online cycling store – sadly its hardly sweat proof, and not even close to rain proof. everything in it gets damp from just riding around in my jersey.
