The Viking Eiger men's active T-shirt is an exceptionally functional short-sleeve base layer designed for dynamic sports and mountain activities across all seasons. Weighing approximately 150 g, it feels light and barely noticeable on the body, while offering supreme thermal balance and protection against chafing. It is designed to act as a dependable "second skin" during running, hiking, climbing, or ski touring.

The shirt is made from an advanced knit fabric with a weight of 217 g/m² and a well-thought-out composition of 55% polyester, 37% polyamide, and 8% elastane. This technical blend ensures efficient moisture wicking to the outer layer, prevents overheating, and reduces the risk of unpleasant odors, while maintaining pleasant warmth on colder days.

A seamless construction with a minimized number of seams and breathable mesh zones in high-perspiration areas ensure flawless comfort without skin irritation. The close-fitting, highly elastic cut adapts perfectly to every body contour and allows unrestricted freedom of movement, making the Viking Eiger T-shirt essential both as a standalone piece and for layering under technical apparel.
