Bergtagen Thinwool SS M
As the lightest first layer in the Bergtagen series, this high-performance t-shirt is perfect for spring and summer days spent in the mountains. Engineered from a lightweight jersey knit that combines the thermal and moisture-wicking properties of merino wool with the strength and durability of polyamide. It will keep you warm when it's cold, and comfortably cool on really hot days. Active fit with good freedom of movement.
