The Shock Doctor X-Fit Cross Compression Jock Short is the ultimate choice in base layer performance. The unique X-Fit Cross Compression Technology keeps muscles stabilized and warms the muscles since the advanced fit mimics the taping methods of the best athletic trainers. X-Fit wraps the hamstrings, quads and hip flexors and provides a whole new level of improved support and circulation. Included is Shock Doctor's AirCore hard cup (in black camo or amoeba camo; image is black camo) that is built and processed with advanced materials resulting in a cup that is 30% lighter to traditional standard cups. While it may be lighter it doesn't lose any impact protection and has a performance fabric and finished edges for a soft feel. The inner fit moves independently from the short, allowing the cup to stay in place throughout a full range of motion so you can capitalize on your stride while protection stays where it needs to be.
