Swampbutt Underwear is made from spandex and lycra to wick and dry visible and embarrassing butt sweat. SwampButt Underwear Declares Bill O’Brien World’s Luckiest Man.
Our SwampButt Underwear™ is made from a blend of spandex and lycra. Spandex provides signiﬁcant strength and elasticity and the ability to return to the original shape after stretching. And like polyester, it wicks moisture and dries quickly. Better still are the variety of colors our SwampButt Performance Underwear comes in.
