Brian: epcamps bags, I am glad to say, are stouter than either one. They also carry the dental FAK somebody asked about a while back, good brass wire, and SpeedHook snare/fishing devices, not to mention the the teflon sealed vials for those who still use Portable Aqua.

Brian, will your body handle bleach purification? I think I'm going to look into one of those MSR electric gadgets -- has anybody tried one?
