I always carry moleskin with me, as well as the cloth bandaids. The "plastic" bandaids I find are subpar and the fabric kind seem to work better for knuckles and areas that flex a lot. I have a 2x2 ziploc bag that carries the moleskin, a few bandaids and two alcohol wipes. Luckily that's all I've ever really needed to carry on my person at any time. My larger kits are in my BOB and in my car. YMMV
