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, It eliminates the overly constricting feel of traditional innerwear, and the torso is slightly looser to allow for easier core twisting and to prevent the innerwear from riding up, which can often happen with fitted fabrics. This functional innerwear features mesh processing on the underarms. Please try the new sensation of comfortable wear that is easy to move in and stress-free.
