Too big
I got these for my son’s sports glasses after he lost the elastic strap that came with the pair. First of all, these were a “Prime Shipping” item and took 5 days to arrive. The quality of the straps seem pretty good. The straps however are way too big. My son has a big head and with these straps shortened all the way there is way too much room. My son wanted the straps to keep his glasses from moving while running/moving. They do not do that because they are way too loose.
