M's Intraknit All-Season Merino Base Layer Bottom
Description
Men's Intraknit™ All-Season Merino Base Layer Bottom
Engineered for high-output activity in variable conditions, the Smartwool Men's Intraknit™ All-Season Merino Base Layer Bottom delivers a smart blend of performance and comfort. Designed to move with you through intense workouts and demanding outdoor pursuits, these base layer bottoms are built to minimize distraction and maximize endurance.
At the heart of this base layer is Smartwool's proprietary Intraknit™ technology, which seamlessly integrates targeted zones of insulation, articulation, and ventilation into a single, continuous knit construction. This means strategic breathability where you run hot and added warmth where you need it most—without the bulk or restriction of traditional layered fabrics.
The fabric blend combines the natural performance properties of Merino wool with TENCEL™ Lyocell fiber. Merino wool is renowned for its exceptional moisture-wicking capabilities, natural temperature regulation, and inherent odor resistance—making it ideal for both short efforts and multi-day use. The addition of TENCEL™ Lyocell fiber enhances cooling and softness, helping to keep skin feeling dry and comfortable during sustained activity.
Minimal seam construction reduces friction and chafing against the skin, a critical feature for athletes and outdoor enthusiasts logging serious miles or hours on the trail. The result is a second-skin fit that stays comfortable across a wide range of activities and temperatures.
