Spyder Freestyler Mens Long Underwear Top

The Spyder Freestyler Long Underwear Top is made for those who want warmth and comfort on the mountain. This top features a nano technology designed to increase the temperature of the fabric by 5 degrees when you're wearing them. How so? It's called THOT and it absorbs solar heat and body heat and uses it to increase the fabric's temperature. Simple as that. Even after you wash it, it'll still work. And you should wash your long underwear after use. Moisture Management allows the sweat to be pulled away from the body to promote additional comfort. The Spyder Freestyler Long Underwear Top also is made with stretch fabrics so your mobility won't be restricted. [+]
