Longer than REC SPEC replacement strap.
I purchased these strap for my small child to use with Liberty MX20 glasses. These straps are sturdy and seem to fit the glasses fine. They were definitely longer than the REC SPEC replacement and perhaps even longer than the original REC SPEC straps (the replacement strap was smaller than the original). I do like the color and low profile - these would be great if they could fit for smaller children. Also, these straps were much more difficult to get on the glasses than the REC SPEC strap.
