Details Insulated baselayers? Yep. That's a thing. The Puffer Pant is a fleece long underwear bottom that's got panels of warm down insulation on the upper half of the pants, where you could use a little extra coverage when riding cold chairlifts or touring on a frigid day. They also do double duty as loungewear in a backcountry hut or on a powder-chasing road trip. Material Furano Fleece: 94% polyster, 6% spandex Pertex Quantum: 100% polyamide 40-gram Greenloft recycled insulation Fit Regular fit: A traditionally cut fit that sits comfortably and true to size. Not too baggy; not too tight. Right down the middle. This standard fit allows for plenty of maneuverability in a classic, everyday shape for daily life and active missions.
