ActiveM. "Look good, even on the inside." This "Comfort Inner" camouflage series combines lightweight, quick-drying, breathable, and stretchy properties with design. ActiveM's lightweight innerwear, without sacrificing quick-drying capabilities, provides stress-free wear that puts less strain on the body. The sleeves are designed for a slightly snug fit to prevent unnecessary muscle movement, while the torso is made slightly looser to eliminate the tightness of traditional innerwear, allowing for easier torso twisting and preventing the common issue of innerwear riding up with fitted fabrics. This functional innerwear features mesh processing under the arms. Please try this new sensation of comfortable wear that is easy to move in and stress-free, unlike anything you've experienced before.
