The Tear-Aid patches from Parktool are super useful to quickly repair small holes in your kite or leading edge. Parktool and M3 joined forces on this one and ensures that they stick extremely well. The self-adhesive pad stretches and bends in every direction. The patches come in sets of 6 and a piece of sandpaper.
Very handy to carry with you in your kite bag if you want to do a quick-fix on a small hole in the canvas or tube, up to 3x3 millimeters.
