We designed the Sasha Fleece Onesie as a technical, super-soft baselayer to wear under your jacket and ski pants in the mountains. But the truth is it’s so darn comfortable, you’ll probably wear this one-piece suit everywhere else, too, like to pick up Thai food or to drop off your skis for a tune. Made from pajama-soft Furano fleece, coated in a DWR, this is basically a modern-day stormproof sweatsuit. A Nature Calls system makes for hassle-free bathroom breaks.
