I carry a nice, compact little kit (6"x3"x4" soft pouch) that goes on the bike easily. It has the normal Band-Aid and antiseptic wipe sort of stuff, but also has larger bandages & wraps, a chemical-activated cold pak, and a variety of sealed ointment & applicator paks with stuff for burns, stings, etc. In fact, this thread reminds me that my kit is about 5 yrs old, may be time to replace it. If I find a link to a good one, I'll post it up. Mike B / Gig Harbor, WA
