Thermal Merino Construction And Comfort
Smartwool leverages ultrafine merino fibers tuned for temperature regulation and long-lasting comfort. These naturally soft fibers resist odor buildup, so you can train frequently between washes without sacrificing freshness.
The Intraknit Thermal Merino base layer uses a finely balanced loft to trap warm air while managing moisture. By moving sweat away from the skin, the fabric maintains a dry, comfortable feel even as your effort level rises.
Intraknit Engineering For Performance And Support
Seamless Structure And Targeted Zones
Intraknit engineering places bonded seams and compression features where you need support most. Flatlock stitching reduces chafing during repetitive motion, helping you stay focused on your technique and power output.
Knit density varies across the torso, offering firm support in key muscle groups and a lighter hand in high-mobility areas. This thoughtful balance keeps the top secure under packs or shells while preserving a full range of motion.
Fit, Sizing, And Layering Readiness
Crew Fit For Versatile Layering
The crew neckline sits at mid-body for adaptable coverage during varied activities. A tailored but not restrictive fit allows insulating mid-layers and shells to slide on without binding or pressure points.
Size Selection And Mobility
Consult the detailed size chart and body measurements to choose between standard and slim profiles. Proper fit maximizes thermal efficiency and ensures the top stays in place during dynamic movements, from ski strides to urban commutes.
