ActiveM. "Look good on the inside too." The "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 slight snug fit to prevent unnecessary muscle movement, while the torso is slightly looser than traditional overly tight innerwear, allowing for easier core rotation and preventing the innerwear from riding up, which can happen with form-fitting fabrics. This functional innerwear features mesh processing on the underarms. Please try this new sensation of comfortable wear that is easy to move in and stress-free!
