BUILT TO LAST Anti-Chafe - helping prevent monkey butt and other forms of weird chafing. We spent three years developing the ultimate combination of compression, moisture wicking and comfort that would live up to our GORUCK standards. Built from the ground up, these compression shorts combine a 240 gram fabric that provides just the right amount of compression with a 100 gram grid mesh that enhances breathability in all the right places. A custom jacquard elastic waistband completes the style with additional quality and comfort. Built to handle your toughest workouts and replace your daily boxer briefs, keeping the chafe away.
