How Swampbutt Underwear Works.
The Science
Men's Performance SwampButt® Underwear Solves A Real Problem!
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.
