  • Designed to look and feel like normal sweatpants
  • They repel rain, wind, snow and fire
  • Soft, engineered fleece inside

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.

Designed for an unpredictable world

It used to be just adventurers or the elite military who would be exposed to perpetual threat. But as risk becomes more commonplace, the clothes on your back need to do more. They still need to be soft, comfortable and warm, but they should be designed with extreme performance capabilities. So all our 100 Year gear is made from materials with properties that normal clothing simply doesn’t have. They’re built to cope with whatever the next century holds.

Built with Polartec technologies

As well as being synonymous with outdoor gear, for the last decade Polartec have been developing flame resistant fabrics for the US military after their uniforms began melting in the intense heat of IED detonations. They work with military partners to develop combat-ready layering systems that protect soldiers from sudden heat sources in hostile territories. Our aim was to let anyone benefit from this technology. So we worked with Polartec to rebuild our 100 Year Hoodie from scratch, then we used the same technology to make these pants.
