M81 Woodland Camo swim trunks in 91% recycled polyester and 9% spandex microfiber, cut with an elastic drawcord waist and an all-over four-color print. Standardized by the U.S. military in 1981, the pattern sets broad green and brown foliage shapes against black branch forms and a sand-colored ground.
The larger woodland repeat remains legible across the front and back panels instead of collapsing into visual noise. Four-way stretch supports swimming and shoreline movement, while the water-repellent surface dries quickly. An anti-chafe mesh liner sits inside the shell; draining side pockets and a compact internal pocket handle small essentials without adding external hardware.
