SwampButt Underwear performance undergarments are made from a blend of lycra and polyester fibers. The traditional brief style is a blend of cotton and lycra. Both styles fit snuggly, there will never be any droop associated with our garments.
The original SwampButt Underwear designs were not as big as most of the American men who suffer from a sweaty backside.  These men need a garment to help them stay dry. In addition to the larger sizes, to accommodate more girth, both leg openings on all the new SwampButt Underwear made in the USA garments are larger than before. Waist sizes are also more forgiving and bigger.
The fabric in the new underwear is from ‘Sportek’, one of the leading manufacturers of sports clothes and fabric anywhere. The material contains 83% polyester and 17% Spandex. This is eight percent more Spandex than used in the original designs, so the underwear is ‘stretchier’ and more forgiving. But there were more reasons we moved production to the U.S.A.
As designers and marketers, we felt that only other Americans could fully grasp the need for a bigger pair of underwear (if only airlines were as thoughtful). The new SwampButt Performance Made in the USA garments are also made with ‘Microblok’ technology to prevent stinky drawers or from the Latin; ubi foetidum. MicroBlok inhibits the growth of bacteria on treated surfaces of products, greatly reducing stains, odors, and product deterioration.
All of this material science, chemistry, design capability and even colorful designs are realized in the new SwampButt Underwear™. We hope you enjoy them
