A new addition to 5.11's Undergear™ collection, they are introducing a Sports Brief this season. The Sports Brief is cut for an athletic fit and is built with state-of-the-art fabrics and manufacturing processes. Their 3D Wicking™ treatment creates a three-dimensional fiber designed to rapidly wick moisture away from your skin, and just as rapidly evaporate that moisture. A blend of 80% polyester and 20% spandex make the briefs stretchable, comfortable, breathable and quick-drying – great for everyday wear or travel. They feature a 1-1/2” quality elastic waistband. Imported.
