the strap is losing elasticity. The straps are removeable and could be used with a newer Flex or Spectra mask.
OK...that just makes no sense. Why not say: "Yeah, the straps are shot, but you could replace the probably perfectly fine strap on your current mask with this old, potentially unsafe one". Honestly, do kids today really put that much emphasis on fashion over function (or safety, for that matter)? Damn kids...
