Icebreaker Merino 125 Cool-Lite Sphere III Short Sleeve Tee

The Sphere III Short Sleeve Tee Mens from Icebreaker is a lightweight, versatile tee designed for outdoor activities. With a blend of natural fibers, it’s meant to help you stay comfortable whether you’re on the trail, training, or just exploring the day-to-day outdoors.

Made from 60% lyocell and 40% Merino wool, this tee offers a soft touch against the skin while managing moisture and odours naturally. The slim fit cut follows your movements without feeling restrictive, making it easy to wear on its own in warmer conditions or to layer under a jacket when things cool down. The clean design, without prints, keeps it understated and adaptable, whether you’re out for a run or grabbing a coffee after a hike.

The 125 Cool-Lite™ construction combines Merino wool with TENCEL® lyocell fibers into a lighter, breathable fabric. You’ll find it moves moisture to the surface where it can evaporate more quickly, helping you regulate temperature on humid days or during high-intensity activities. TENCEL® itself comes from sustainably sourced wood pulp and adds strength and softness, while the Merino fibres deliver natural odour control and gentle warmth.
