REI Silk Long Underwear Bottoms - Men's

Product Descriptions

REI Description: The REI Silk long underwear bottoms are smooth, soft and incredibly comfortable. They'll help keep you warm on a cold day and they work great under additional layers. Lightweight, breathable, pure silk jersey is enhanced with a wicking treatment to help keep you dry and warm; plus, they dry quickly. Wide, self-fabric elastic waist, seamless sides and rib-knit cuffs provide a comfortable fit throughout. Fabric is substantial yet thin enough for everyday wear under jeans or casual pants. Machine wash warm on gentle cycle without bleach or fabric softeners; tumble dry low.
