Our 100 Year Sweatpants have always been tough. But these sweatpants are the softest and lightest version we’ve ever made. They’re super stretchy, fleece-lined, breathable, and they come with five pockets to store all your valuables. But the pants are also windproof, abrasion resistant, water repellent, fire resistant, and can withstand temperatures 4x hotter than the sun. So it’s fair to say they’re an upgrade.

The sweatpants combine 4 different layers of technology. The inside of the sweatpants are made from an incredibly dense fleece that’s 4x more windproof than a regular fleece, while the outside of the fabric is a blend of modacrylic and aramid fibres for fire resistance. On top of that there are two coatings. One is a fluorocarbon-free treatment that helps it shed rain and snow. The other fuses high strength polymers directly into the fibres to make the sweatpants highly abrasion resistant.
