Ironraven is right on with his review (IMO). I have one that is in servcie as an extended stay toilietry kit, has my toiletry stuff with snivel stuff added (OTC meds, blister care stuff, bug spray, etc). I found mine is garage sale for $2 and it was worth it... dunno if I'd pay more.

There are so many good bags out there, I also agree with Ironraven about the EOD bag, I have one that is my Shotgun SHTF bag. Well built and cheap. The others that have been recomended are good choices also. NARESCUE's Fanny Pack is a good design for a medium to large size survival kit. It is small enough to use as a pullout from a larger backpack and big enough to build a decent kit in. They make one in Orange too if that is you cup of tea.

Your options are limitless... and you are in a good place to bounce ideas!
