No suggestions off the top of my head... one of our flight Paramedics made the strap on survival kits we use. I do have a combat medic thigh pack for my W-EMT gear, but it requires a belt to hang from. I hadn't thought about it, but I suppose you could make a thigh belt with 1 1/2 inch webbing and fast-x buckle... I just hadn't thought about it. Now that I'm thinking about it, you could take something like this bag from REI, add thigh straps and have a nice little kit. For that matter you might be able to take a fanny pack and convert it to a thigh pack... or wear it as a fanny pack...

MNS

P.S. Sorry, I'm hungover this morning... thinking about anything is quite an accomplishment, LOL!
