ActiveM. "Look good on the inside too." The "Comfort Inner" camouflage pattern series combines lightweight, quick-drying, breathable, and stretchy properties with design. ActiveM's lightweight innerwear, without sacrificing quick-drying performance, achieves stress-free wear that puts less strain on the body. The sleeves are designed to be slightly fitted to prevent unnecessary muscle movement, while the torso is slightly looser, overcoming the tightness of traditional innerwear and preventing the innerwear from riding up, which can happen with fitted fabrics, and allowing for easier torso rotation. It is functional innerwear with mesh processing on the underarms. Please try this new sensation of comfortable wear that is easy to move in and stress-free, unlike anything you've experienced before.
