ActiveM. "Look good, even on the inside." The "Comfort Innerwear" camo series combines lightness, quick-drying properties, breathability, and stretch with design. ActiveM's lightweight innerwear, without sacrificing quick-drying properties, achieves comfortable wear that puts less strain on the body. The arms have a slightly snug fit to prevent unnecessary muscle movement, Eliminating the overly constricting feel of conventional innerwear, the torso is made slightly looser to facilitate core twisting and prevent the innerwear from riding up, which often occurs with fitted fabrics.
