Wrapz Floating Neoprene Strap. The WrApz Head Strap is designed to help keep sports glasses in place on the head in active sport. Ideal for Paddleboarding. For smaller heads or a very tight fit you can trim the ends back slightly as the neoprene won't fray however if you do this you will need to secure the cut stitching again with a couple of stitches or a drop of glue to stop it loosening.
