Designed for men who hike or enjoy outdoor activities on a daily basis, the Icebreaker M 150 Tech Lite SS Tee Pure Altitude combines the natural qualities of merino wool with a unique graphic design inspired by Mont Blanc. Lightweight and breathable, it’s ideal for both mountain excursions and everyday wear, thanks to a fiber that naturally regulates temperature and moisture without relying on synthetic materials.

Merino wool delivers natural performance in the Icebreaker M 150 Tech Lite SS Tee Pure Altitude

Made from 100% merino wool, this T-shirt harnesses the inherent properties of this fiber to meet the demands of physical activity. Merino wool naturally regulates body temperature, keeping you comfortable during both sustained exertion and rest periods. Its ability to wick away moisture helps maintain a lasting sense of comfort, even when you’re sweating. The natural odor resistance characteristic of merino wool keeps the garment fresh between washes—a practical advantage for long outings or travel.

A design tailored for movement and carrying a backpack

The regular fit and crew neck offer a simple, versatile silhouette suitable for both hiking and urban wear. The offset shoulder seams reduce friction in the areas where backpack straps exert the most pressure—a technical detail that’s particularly useful during mountain outings. Weighing approximately 147 g, the T-shirt takes up minimal space in your pack and doesn’t add significant weight to your overall gear.

A Natural Material and an Original Design

The merino wool used is a naturally renewable, recyclable, and biodegradable fiber under certain conditions, free of plastic microfibers and petrochemical-derived materials. The Pure Altitude design, which gives the model its name, is an original artwork depicting Mont Blanc, combining photographic elements and hand-drawn details. This design sets the T-shirt apart from technical apparel, which is typically more neutral in style, without compromising its performance.

The Icebreaker M 150 Tech Lite SS Tee Pure Altitude should be machine-washed in cold water without fabric softener and line-dried in the shade, following the manufacturer’s instructions to preserve the merino fiber over time.
