This men’s long-sleeve thermal base layer utilizes a dense knitted polyester weave to trap essential body heat while rapidly transferring moisture away from your skin.
- The engineered knit structure flexes alongside your joints during dynamic movements, preventing bulky seams from catching on your outerwear layers.
- Polyester fibers actively draw perspiration off your upper body, keeping your base warm enough for early morning runs without becoming damp.
- A tailored cut follows your natural shoulder lines and arm span to eliminate friction when you zip up heavy coats over your chest.
- The technical fabric construction breathes efficiently, enabling you to regulate your core temperature precisely during sudden bursts of physical exertion.
