This video goes over what is in the bug out bag first aid kit. The kit itself weighs just 11oz and is 100% waterproof up to 150ft.
This waterproof 43 piece kit was put together with bugging out in mind because size and weight do matter. There are 100 different little things that make up a good bug out bag first aid kit and it can cost quite a bit to but these pieces individually.
This individual first aid kit is available at the SHTFShop.com now. http://www.shtfshop.com/product/bug-bag-first-aid-kit/
