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

The Icebreaker Merino 125 Cool-Lite Sphere III Short Sleeve Tee stands apart from typical hiking tees by blending premium ZQ-certified Merino wool with TENCEL™ Lyocell in a featherlight 125 gsm knit. The result is a base layer that feels cool against the skin on warm ascents, yet insulates when temperatures dip. Its Metro Heather colorway offers a versatile, understated look for trail and town alike.

Highlights

• Cool-Lite™ fabric: 60% Merino wool, 40% TENCEL™ Lyocell for natural temperature regulation
• Ultra-light 125 gsm weight—breathable and quick-drying for high-output activities
• Odor-resistant Merino wool keeps you fresh over multi-day treks
• Offset shoulder seams prevent pack rub and chafing under straps
• Dropped front and back hem provides extra coverage when reaching or bending
• Regular fit with crew neck and short sleeves for unrestricted movement

In daily use

From summer hikes to travel days, this tee excels as a next-to-skin layer. The Cool-Lite™ blend actively wicks moisture away from the skin, while the breathable knit allows excess heat to escape. Merino's natural odor resistance means you can wear it longer between washes—ideal for minimalist packing. The soft, ultra-smooth hand feel eliminates itch, and the offset seams keep you comfortable even under a loaded backpack. Whether layered under a shell or worn alone, it adapts to changing conditions with ease.
