Welcome to the store! Self-Adhesive Nylon Repair Patches (Peel and Stick) Water-Resistant Patches Suitable for down jackets, vests, tents, sleeping bags, etc. It's really important that you follow the instructions (as pictured) to ensure the best results. Please Note: These patches are not guaranteed to work on all types of fabric. As you hopefully 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 sample piece of nylon material. That patch has been in place for over 2 years. However, they struggle with very waterproof fabrics (i.e., where the water bubbles upon 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 as a fix, rather than 50 - 200 on a new jacket or vest. My offer is to provide a number of colors at a cheap price and to offer a fix for down jackets. As above, this is not guaranteed to work on all fabrics, so please check if you think the patch would adhere.
