Like an idiot I got my enlightened equipment jacket sleeve way to close to my cook stove, and melted a small hole in the wrist of the sleeve. This patch kit was super easy to use and the self stick patch works great. It has already lasted through a couple rough hikes AND my everyday use of the jacket. I highly recommend everyone who uses EE gear buys this kit ahead of time just in case. My only complaint is that it only comes in black, and my jacket is green, but for a person who cares more about utility over looks, like myself, it’s no problem at all.
