This Innovative Base Layer Is Designed for Thermoregulation

It’s great fun picking out a winter coat with the most technically advanced features possible, but the oft-neglected base layer selection is equally important. A good base layer should not only provide warmth but ample ventilation as well, which Smartwool’s new Intraknit 3D-knit Merino wool base layers were designed for. They’re built with an articulated performance fit and gender-specific ventilation placed for optimal thermoregulation, keeping you warm where it matters most. The Intraknit Merino wool layers are flexible and breathable, with durability, odor resistance and faster dry times. You won’t get these features from your old pair of long johns, and if you’re going to be performing strenuous activities in the cold, you’re going to seriously appreciate the difference.
