I use while cycling with prescrip sunglasses...doesn't snug-up but, cotton on earpiece works well to keep glasses from slipping down while riding.
I love this retainer! I was tired of the tail hanging down my back. It just annoyed me. These are perfect and I like that they are adjustable and no annoying tail! Thank you Chums!
Exactly what I was looking for and it did not disappoint. Bought one for my sister and she loves it as well!
While it works smoothly, it is not designed to close up snugly behind head for active pursuits, which seems a natural use for this tail-less design.
