Best IFAK you can get: http://www.condoroutdoor.com/ma41rip-awayemtpouch.aspx
It can hold a ridiculous amount of stuff and the rip away feature is great. Had it in Afghanistan and now it's filled with everything you would encounter on a hiking/backpacking trip up to GSWs and trauma. Detached it sits in the trunk of my car and when I go camping or hiking I simply attach it to the velcro base that's MOLLE'd on my bag.
Inexpensive and can fit a lot of stuff in a small package. Also folds out to three sections so you see virtually everything packed in the kit.
