Whether we rock it as a warm - up for the gym, layer it under our shell bibs on a ski day, or slip into it on a lazy Sunday morning, the Backcountry Meltdown Water - Resistant Pant keeps our bottom half feeling its best both indoors and out. The polyester fleece fabric is super - soft and offers plush warmth in cool temps, while the Pfc - free Dwr treatment sheds any light moisture we might encounter on our day out.
