Never been used tennis elbow support, it's small to very small, I cannot get my hand into it, would suit youth or small framed adult.
Wetsuit material with a sort of velour inner, the support goes over the elbow and is tightened over the forearm with the Velcro strap.
Though never used, it was at the bottom of my first aid kit and I have washed it to freshen up.
Perfectly sound if not perfectly aesthetic
