Threadlock Patch
A small tear in a pack, jacket, or tent canopy spreads with every mile if it isn't sealed. Off-the-shelf nylon patches sit on top of the weave and lift; the adhesive doesn't grip. The Threadlock Patch uses a woven polyester carrier paired with a proprietary pressure-sensitive adhesive that wets into the host fabric, so the patch flexes with the gear and behaves more like a graft than a sticker. 0.28 g per patch, 36 × 28 mm, 0.14 mm thick. 12 per pack. Two-piece waxed paper liner for clean one-handed placement. Use immediately; full bond strength at roughly 4 hours. See Patch Science: Threadlock vs. Airlock for the breakdown. For inflatables, use the Airlock Patch. Both ship inside the Repair Spool and First Aid & Repair Kit.
