Interval Long Sleeve Shirt – High-Performance Training

Built for high-intensity interval training and versatile enough for everyday wear, this long sleeve performance shirt uses a four-way stretch fabric that moves with your body through every rep, sprint, and stretch. The lightweight polyester-spandex blend wicks moisture rapidly and quick-dries, preventing the heavy, clinging feel of sweat-soaked cotton. A mesh panel under each arm promotes ventilation during peak exertion, and the flatlock seam construction eliminates chafing across the shoulders and torso. The raglan sleeve design frees the shoulder joint for overhead movements, making this shirt ideal for CrossFit, weightlifting, running, or tactical training. A small zippered pocket at the right hip provides secure storage for keys or cards without adding bulk. The shirt is available in Black and OD Green, both subdued colours that work well in gym, field, or casual settings. Sun-protective fabric is woven into the construction, not applied as a coating, so it remains effective through regular washing. The slim athletic cut layers comfortably under jackets or hoodies without excess fabric bunching.
