I'm a long time reader and love the SurvivalBlog site. I really wanted to point out one little thing that I think is a very important item in any kit: Coban Wrap. (Sold under several brand names.)
I'm a former medic and now live in the northeast on the water. I have young kids and we do some of boating and spend a fair amount of time on the remote rocky beaches of the area. When we got here earlier in the year I put together a little first aid kit focused on multi-use items and scalability and try to keep it with me especially when we're far from emergency services. I broke into the kit a lot this summer and the one thing that stood out was how glad I was to have Coban.
Coban's a self adhering wrap and I've been impressed its versatility for a while. This last summer I used it many times.
Here's what it came out of the kit for this summer (these are off duty situations):
That's what I actually used it for in just one 2-month period as a civilian... In more dire trauma situations it's an extra hand when there are multiple wounds and holds things together a lot faster than tape. Many problems big and small can be addressed with a roll of Coban and a trauma pad and I keep both of them even in my smallest kit.
Suffice to say that I think the versatility of Coban is worth noting especially since it is rarely supplied in stock first aid kit lists. I'd urge folks to consider adding it to their kits.
