Great glavins’ ghost! The science of SwampButt Underwear.

How it Works
What Is SwampButt Underwear Made From?
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.
How Does SwampButt Underwear Work?
How the undergarment works and what it is made of are related. First, there is the phenomena of ‘wicking’ which is the way moisture travels across a larger area of fabric. The more and further moisture (in this case sweat) can disperse across a surface, the faster it can evaporate. Imagine a squeegee pulling water across a windshield. When spread to a larger surface are, the water on the windshield evaporates faster. Or push rain water across a drive way or parking lot into a larger surface area and it also evaporates faster.
The same thing happens with our garment. Sweat wicks across a larger area and evaporates faster because of this. The rate of wicking is related to the materials and the way sweat spreads across them. Polyester fibers are hydrophobic because they are really plastic and will not absorb moisture. Our performance undergarments are made from lycra and polyester fibers. The brief style from cotton and lycra.
