The Base Haven is breathable, durable, and moisture wicking, and that's just the beginning. This baselayer pant is comfortable enough to wear around the camp or around the house and versatile enough to keep you warm and dry when the temperature drops and you have to layer up. The synthetic blend moves with you, so it won't slow you down or restrict your movement. | Pnuma Outdoors Base Haven Base Layer Pant in Grey | Size Large
