I am going to echo what nitesite said. A speedstrip fits perfect in a watch pocket. I also have a little zippered forearm pocket on a jacket I use a lot that I will stash a speedstrip in as well.
It is slower that a speedloader, but with practice, you can charge a revolver surprisingly quick.
I use them a a handy way to carry extra ammo for my .44 hunting revolvers. That way I never have to fish for loose rounds.
