Terramar makes the best silk long johns for outdoorsmen that prefer natural, breathable undergarments. Silk long underwear is surprisingly lightweight while keeping you warm, dry and comfy. Silk jersey has a thin profile that fits under your regular clothes to keep you warmer indoors or out. Terramar’s Thermasilk Pants keep your legs warm and toasty without the usual bulkiness. Wear it with the matching crew top for full body coverage.

Spoiler Alert! If you start wearing your long undies to bed, you’ll need to get an extra pair or they might never make it to the laundry.
