Moisture-wicking underwear for men who sweat – even when
sitting, commuting, or working all day.
Swamp butt is the informal name for the sweaty, sticky feeling around your buttocks and between your cheeks when moisture builds up. It can leave underwear damp, make sitting uncomfortable and sometimes show through your pants. The name is funny. The feeling usually isn’t.
Heat, exercise and clothing that traps warmth and moisture can leave your backside feeling swampy. Humid weather makes it harder for sweat to evaporate, while damp underwear can prolong that uncomfortable feeling.
You might notice it during yard work, a round of golf, your commute or a long day on the job.
Start with clean, dry skin. Change out of wet clothing, choose outerwear that allows airflow and look for underwear designed to move moisture away from your skin and dry quickly.
SwampButt Underwear is designed to help manage that moisture and keep everyday sweating more comfortable. Its moisture-wicking performance fabric spreads sweat across a larger area to support evaporation.
Your body will still sweat. The goal is to manage the moisture and reduce the damp, sticky feeling that comes with it.

SwampButt Underwear performance undergarments are made from a blend of lycra and polyester fibers and chelated silver. SwampButt Underwear fits snuggly, does not droop or bunch up in a wet knot between the thighs like traditional men’s underwear does. SwampButt Underwear is made in the USA.
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.
