I was sewing a new patch on my pack today and superglued the patch b4 sewing. The mixture of superglue and the ripstop nylon on the side of the pack was so strong it first broke a sewing needle, then it broke my thickest upholstery needle. Yet it still bends and moves. Whats the deal, is this a way to make our packs bullet proof, or is the glue going to weeken quickly leaving it how it was?
