The Sensor Merino Air men's long sleeve shirt is designed for mountain and endurance sports enthusiasts looking for a premium, breathable, and featherlight base layer. It is made from an advanced single jersey knit with an exceptionally low fabric weight of just 120 g/m², with the entire shirt weighing a mere 145 g. This minimalist construction delivers an unmatched lightweight feel against the skin and provides optimal thermal balance both during high-intensity summer activities and as a technical base layer in winter.

The core of the fabric consists of a sophisticated hybrid blend combining 90% merino wool and 10% polyamide. Ultra-fine New Zealand merino wool fibers with a diameter of 17.5 microns ensure complete softness without itching, excellent breathability, and natural antibacterial protection that effectively neutralizes odors even during multi-day wear. The addition of durable polyamide filament significantly enhances the elasticity, mechanical durability, and dimensional stability of the material, while also ensuring exceptionally fast drying.

The refined slim fit with an anatomical cut closely follows the body, allowing unrestricted freedom of movement when running, hiking, ski touring, or cycling. Flatlock seams prevent chafing even when carrying a heavy backpack, ensuring supreme comfort, while reliable UV protection rated at UPF 25+ ensures worry-free movement under the intense alpine sun.
