The Merino Blend 125 Cool-Lite™ Speed Short Sleeve Tee is icebreaker’s lightest, most breathable performance tee, made entirely of Cool-Lite™eyelet mesh for ventilation and temperature regulation. In a shorter length, closer-fitting design and constructed with movement in mind, it's ideal for running and other high-intensity pursuits in warm conditions. This tee’s Cool-Lite™ eyelet mesh fabric uses a lightweight and breathable TENCEL™ Lyocell and merino wool fabric blend that dries quickly and helps to keep you cool. Offset flatlock seams enhance fit and help reduce friction, while 360° reflective details keep you visible in low light conditions. Soft merino wool and TENCEL™, a sustainable plastic-free lyocell, combine to create icebreaker Cool-Lite™, a lightweight, breathable and quick drying fabric. Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics.
