These patch kits are a heavy duty fire resistant nylon material with a very strong and durable adhesive. They come in a heavy duty rubber pouch that is designed to allow you to put them in a back pocket or in your gear and not worry about them getting wet or damaged, even when run through the wash. Just put these in your gear and forget them until you need them- but when you need it you will be happy it is there.
On clothing these will last through 2-3 wash cycles with just the adhesive typically, showing you how strong it is. You can sew the edges later to make it a permanent patch too, so you can quickly apply it on the go and worry about sewing later when you have time. On gear it can patch packs, pouches, jackets, ponchos, tarps, tents-
anything fabric it can do. You can also apply them to areas of your gear that rub as a preventative so that the patch wears instead of the item, such as on a pack where it rubs the frame.
These are real military issue, made in the USA gear. Check out the video to see more about them. Sure, the ACU pattern doesn't match a lot of gear, but lets get real- performance matters more than fashion, and the small patch not matching isn't a big deal when you can get them at this kind of price and when it saves your butt in the middle of the field, a camping trip or long work day.
