As with any iron-on patch, it doesn't hold up that well to constant washes. That being said, if you stitch it on, it lasts as long, if not longer than if the garment were new. Highly recommend stitching instead of ironing if you'll be washing the garment constantly.

Didn't stay on my pants after multiple washes. Still holding onto my jacket (but I don't wash that).

It was just what was needed for repair. Strong and sturdy.

Happy that patches are available finally. They are working so far I've been in the field pouring concrete for last 30yrs

Did what I expected from Carhartt
