I added a tourniquet, a couple packs of Celox Granules, and a note pad. (For “SOAP” notes and recording other info when needed.) I don’t believe I can get much more in.... not that I need to. Pretty much has everything I need. Wanted something for our wilderness excursions but nice to have in the car as well. Very happy with the kit. I would have given 5 stars except after ordering, I had no idea when I would receive it. I wouldn’t mind waiting for it but would like to be informed.
