Mary-Kate and Ashley Olsen’s clothing brand The Row isn’t one of those fashion companies that half-asses anything. The twin sisters behind it started the brand because they couldn’t find the perfect t-shirt. Twelve years later, they’ve perfected everything from jeans to knitwear to leather backpacks and beyond — for women.

It’s why guys in the fashion space got so excited when the Olsens announced they were ready to release a full menswear collection, which focuses on wardrobe staples. They scoured the world for the best suppliers and factories to work with, and chose some of the greatest materials on the planet to use in their debut line. It’s why the $5,250 bomber jacket they made marries supple Italian suede with merino ribbing, and why even the plain white t-shirt in the collection goes for $350.

The sweatpants, which cost more than the Japanese selvedge denim jeans in the collection, are cut from a cotton jersey that’s backed with a soft cotton fleece. They have an elastic waist and a functional fly that’s finished with an actual zipper. They’re what sweatpants look like when taken to their nth degree — and if you’re lucky enough to snag a pair before Mr Porter runs out of them, you’ll never want to take them off.
