The men's long-sleeve base layer Thermowave Originals is a reliable and versatile first layer of clothing for all cold-weather outdoor enthusiasts. It excels in winter sports, running, hiking, cycling, and all dynamic outdoor adventures where rapid moisture wicking and maintaining optimal body temperature are essential.

Crafted from 100% functional polyester with a fabric weight of 180 g/m², it provides an ideal balance between thermal insulation and low weight, weighing in at only approximately 180 g. The special knit structure creates micro air pockets that trap body heat while accelerating sweat evaporation outward, keeping your skin dry even during the most demanding ascents.

The ergonomic, body-mapped fit (next-to-skin fit) combined with 4-way stretch fabric offers complete freedom of movement without uncomfortable restriction. The shirt features raglan sleeves, an extended back panel that reliably protects the lower back from cold drafts, and flatlock seams that prevent chafing and skin irritation under a backpack or outer layers.

For long-lasting freshness, the advanced SILVERPLUS® silver ion antibacterial treatment effectively inhibits the growth of bacteria and unpleasant odors. Thanks to quick drying and easy care, this shirt is an indispensable technical piece for multi-day treks and everyday outdoor recreation.
