Well, I've refitted my Large Personnel Survival. I use this kit as a backup for gear I already have with me in the field. A couple items you won't find in this kit are a Signal Mirror or multi-tool, these items reside in my pockets. This kit will fit in a BDU pocket but is bulky, it does fit nicely in the side pockets of a CamelBak BFM or my SoTech SAR vest. I have it setup st that it can be grabbed in a hurry should I need to dump my pack of vest.
