Self-adhesive nylon repair patches (peel and stick). Water repellent. Suitable for down jackets, vests, tents, sleeping bags etc. It is very important that you follow the instructions (as per the image) to ensure the best results. Please note: These are not guaranteed to work on all types of fabric. As you probably understand, there are hundreds of types of fabric and this is one type of patch. They have worked on my Rab jacket and also on a number of test fabrics. The last pictures show them attached after 6 months on a test piece of nylon material. That patch has been in place for over 2 years. However, they have difficulty with very waterproof fabrics (i.e. where water bubbles on contact with the fabric and is not absorbed). The purpose of the product is to offer a cheap alternative to replacing a jacket (i.e. ~3 for a repair, instead of 50 - 200 for a new jacket or vest. My offer is to provide a number of colours at a cheap price and to offer a repair for down jackets. As above, this is not guaranteed to work on all fabrics, so please check if you think the patch would stick.
