Sub Zero Merino Wool Mens Long Sleeve Thermal Base Layer Tops are not only produced from the worlds finest and softest Merino wool, they are also manufactured using state of the art technology. Utilising whole garment knitting machines means that there are no seams at all in the garment - not even on the arms or shoulders! This process also allows us to knit features in to the garment that will aid the wearer, such as rib zones along the shoulder and arms for support, a contoured back drop, low profile neck, and thumb holes.
The Sub Zero Merino Wool Base Layers are ideal for hikers, skiers and mountaineers who want to wear natural fibre thermal underwear with the performance of a synthetic garment.
Please note: These garments are not suitable for flame retardant applications due to the Lycra content.
