A pack of 5 clear 75mm diameter repair patches. These work brilliantly to repair drybags and the clear windows on our Gourdon rucksacks as well as damaged tents and ground sheets. Also works on water containers with leaks, cracked buckets etc. which you can use to cover over leaks and rips on a wide range of surfaces, like leather, nylon, coated and uncoated fabrics, plastics, glass, metal, wood and much more. These patches are made from the same material as Stormsure Adhesive, so it is flexible stretchy, abrasion resistant and very strong. Clothing with repairs, made using these patches can still go through the washing machine.
