2XU\'s Compression Tights utilise PWX FLEX fabric to wrap and support the major muscle groups allowing them to fire more efficiently, while promoting increased circulation to reduce fatigue and increase power. Graduated compression increases blood circulation for improved recovery, reducing muscle damage and fatigue. Perfect for training, competing, and recovery. 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.
