The Super.natural Sierra140 Men's Merino Short-Sleeve T-Shirt represents a perfect fusion of the natural properties of wool and the premium performance of modern synthetic fibers. Created for dynamic outdoor enthusiasts, it is an exceptionally lightweight, breathable, and versatile piece of technical apparel. Weighing just 215 g, it can be used as a reliable technical base layer for mountaineering, ski touring, or hiking, as well as a standalone, stylish shirt for sports and everyday wear on warmer days.

The shirt is crafted from an advanced 140 g/m² knit fabric combining 50% merino wool and 50% polyester. Fine merino fibers provide natural thermoregulation, breathability, and effective odor resistance by preventing bacterial growth, while polyester enhances elasticity, abrasion resistance, and ensures lightning-fast drying. Built-in UV protection with a factor of UPF 40+ ensures safe movement under intense mountain sun.

A technically refined, athletic cut follows the body's natural lines to offer unrestricted freedom of movement during any activity, while meticulously crafted flatlock seams prevent pressure points and chafing, even under the straps of a heavy backpack. Unlike delicate wool garments, the Sierra140 series is exceptionally easy to care for: it is machine washable at 40 °C and can even be tumble dried, retaining its original shape and softness.
