Sweatpants? There's no sweating here. Joggers? Jog in them and we'll sue. These are Long Jambys. Long Jambys are made out of the same super-soft Jambys material, creating a lightweight and breathable pant that's perfect for wearing inside during cooler weather. You can wear them with or without underwear. You could even wear them with Jambys underneath, you crazy son of a gun. Materials: 95% Modal, 5% Spandex, knitted into a sumptuous French Terry. Long Jambys are designed to graze the ankle for optimal comfort. Inseam lengths are approximate due to the natural stretch to the fabric. Thanks to the design of the pant and elastic, this product fits comfortably in two sizes for most customers — size up if you're in-between or want a more classic "sweatpants" fit!
