Interval Long Sleeve Shirt – Four-Way Stretch 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 features moisture-wicking fabric that keeps you dry during activity. A mesh panel under each arm promotes ventilation during peak exertion, and the flatlock seam construction reduces friction across the shoulders and torso. The raglan sleeve design frees the shoulder joint for overhead movements, making this shirt suitable for CrossFit, weightlifting, running, or outdoor 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 Olive Green, both subdued colours that work well in gym, field, or casual settings. The slim athletic cut layers comfortably under jackets or hoodies without excess fabric bunching.
