Icebreaker Merino 125 Cool-Lite Sphere III Short Sleeve Tee - Midnight Navy Heather - Men's M

Overheating on the trail or during travel often comes down to a single layer—your base tee. The Icebreaker Merino 125 Cool-Lite Sphere III Short Sleeve Tee solves that with a featherlight 125 g/m² blend of 60% merino wool and 40% TENCEL™ Lyocell, engineered to keep you cool, dry, and odour-free from dawn hikes to long-haul flights.

Who is it for

Built for active men who need one shirt that does it all: hikers, travellers, commuters, and anyone who layers in changing conditions. The regular fit and crew neck make it a versatile base layer or standalone top in mild to warm weather.
