The Nike Element Half-Zip features long raglan sleeves and a stand-up collar for warmth when you need it. For reduced irritation and great range of motion, this shirt has ergonomic seaming that maps the natural contours of the body. And flat-seam construction on the sleeves also reduces irritation and enhances mobility. Dri-FIT fabric helps you stay dry and comfortable by wicking sweat away from skin to the fabric's surface, where it quickly evaporates. Plus, it's soft against your skin for comfort. For extra ventilation in high-heat zones, this shirt features mesh underarm panels. And elastane adds stretch, enhanced range of motion and a comfortable, athletic fit.
