The Launch SW 5" Shorts from Under Armour are constructed from an ultra-light, stretch-woven fabric that provides total unrestricted movement. A 4-way stretch is also added to the shorts and works in tandem with the woven fabric to help the garment move better in every direction. This construction allows you to move and stretch freely without encountering any restrictions. A moisture management system resides within the fabric and works incredibly hard to wick sweat as it's produced. Once wicked, the sweat is transferred to the outer layers of the fabric where it can be easily evaporated, ensuring you stay cool, dry and comfortable.
