I read an article about zipstitch in the new USCCA magazine and decided to order some for my first aid kit. A bit pricey, but USCCA members get a 20% discount and it still is a lot cheaper and quicker than going to the emergency room to get stitched up, especially if you live in the boonies of Puna. One kit will stitch up to a 1.5 inch cut. I bought four kits.
