I love this wing patch! It is thick and high grade materials. It does have adhesion on the back, if you want to apply it with heat, but I suggest doing that, as well as stitching it on. This is the second wing patch that I have ordered. The first one, I applied to a black jean jacket. I love the M&S denim jacket, but am pretty fussy about materials and fit, so I found a jacket that I liked and made my own M&S black wing jacket. As with all of their products, they are all high quality.
