My daypack FAK is the AMK 0.7 (I think). It's fairly robust for the bumps and bruise category. I added in an older USGI trauma bandage (prior to the Israeli bandage being standard issue). I typically have a triangle bandage too - this thing is likely Vietnam era, cotton, been with me at least 20 years as my "do everything" rag. Honestly, it's an amazing piece of kit. Bandage, compress, strap, bandana for nose or on my head for a hat, wet it down when hiking and throw over my neck, kleenex, pot holder... those are what I've used it for just what I can think of right now. Anyway, back on track, the 0.7 is in a great bag that just barely squeezes in that trauma dressing. I think I have a 3" ACE wrap in it too, but can't remember, and it's only sitting about 12K miles away right now.
Anyway, if you want to discuss pro's/con's of some FAK items, feel free to PM me. Might take me a couple days to get back, but I'm a total first aid kit-[censored]. I have one in my truck, one in my garage, 2 backpacking kits (the 0.7 and one built into the old USGI plastic kit), and 2 sitting under my bunk right now a foot away. Not to mention my issue IFAK. Believe me, I know gauze...
