The 2XU LOCK Compression Tights take compression to the next level with the new LOCK technology for activities with explosive power. The ultimate zonal support to lock muscles in place and protect against damage. Your 2XU Compression garment should fit the body snugly and firmly without uncomfortably \'cutting in\' to the body. If this is the case, you should review your size choice. For specific sizing, please refer to our Size Guide below, taking into consideration that if you\'re near the borderline for sizes or you wish to wear your compression garment primarily for recovery purposes, be sure to choose the smaller size where possible.
