R1® tops work so well under the fishing jackets, Patagonia decided to extend the experience downward. Patagonia found that lightweight fleece pants, made from the same comfy, stretchy 6.8-oz 93% polyester (41% recycled)/7% spandex fabric, feel just as good under waders and rain pants. In fact, the high-wick/low-bulk performance of the R1 Pants is the perfect combination whenever rigorous wading or extended hikes come into play. Two front pockets hold keys and cash. Elastic waist with drawcord adjustment minimizes bulk and keeps the moon at bay. Inseam (size M) is 32".
