As you can hopefully appreciate - there are 100's of types of fabric and this is one type of patch.They've worked on my Rab jacket and also a number of test fabrics. 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 (i.e. ~3 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.
