Some of my jerseys, and nearly all of my shorts have silicone grip strips on them to hold them in place. I have a couple of jerseys that I love, but I'd love them more if they would STAY PUT, and not ride up. So... I looked around at my local sewing/craft store and found nothing, did a google search and couldn't find anything either.

Has anyone seen gripper strips that can be sewn on to garments?

For example, I have this jersey, and love that the back side of it has a strip of silicone gripper material on the bottom edge to keep it in place.

Does anyone know where I can find something like this to sew into a jersey that likes to ride up?
