The "Shock Doctor Power Supporter with BioFlex Cup" is very comfortable and provides great protection. I wear this for sparing in TaeKwonDo and find that it does not hinder my movement at all. The supporter material is high quality and the sizing is accurate (at least for me in XXL). The BioFlex Cup is lighter than other cups I have used, but is still strong enough to protect me from a fairly solid kick.

Highly Recommended!
