Nylon self adhesive repair patches (peel and stick)Self adhesive patchesWater resistantSuitable for Down Jackets, gilets, tents, sleeping bags, etc.It"s really important that you follow the instructions to make sure you get the best results.Please note: These patches aren"t guaranteed to work on all types of fabric. As you can hopefully appreciate The last few pictures show them adhering after 6 months on a sample piece of nylon material.that patch has been in place for over 2 years.However, they do struggle with highly waterproof fabrics (i.e. where the water bubbles on contact with the fabric and doesn"t soak in).The intent of the product is to offer a cheap alternative to replacing a jacket as a fix, rather than 50 - 200 on a new jacket or gilet.My offering is to provide a number of colours for a cheap price and to offer a fix for down jackets. As per the above, this isn"t guaranteed to work on all fabrics, so please sense check whether you think the patch would adhere.Patch sizes:25x14.5cm
