The Merino Blend 125 Cool-Lite™ Sphere Long Sleeve Tee is a soft, comfortable and versatile performance tee for running, hiking, and any active pursuit in warm conditions. This tee features icebreaker’s jersey Cool-Lite™ fabric, which blends TENCEL™ Lyocell and merino wool to naturally keep you cool and odour-free when you’re on the move. Offset shoulder seams reduce friction when wearing a pack, and a droptail hem offers added coverage.
Soft merino wool and TENCEL™ Lyocell, 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.
