100 Year Sweatpants. Weatherproof sweatpants that keep out winter fires, wind, snow and cold. Join the waiting list.

After spending two years in R&D rebuilding our 100 Year Hoodie to combat fire, rain, wind snow and cold, we decided to take the same technology and use it to make a pair of weatherproof sweatpants. While the 100 Year Sweatpants look and feel like a normal pair of sweatpants, they’re infinitely tougher, as they’re built from a material that started life in a warzone. Constructed from a three-layered fabric originally developed for the elite military, every pair is milled in the US before being manufactured at one of the most technologically advanced factories in the world. With a soft, warm, engineered fleece next to your skin, water repellent membrane and fire repellent outer shell, these warm winter sweatpants are designed to last for the rest of your life. The waiting list is now open.
