A second layer that keeps you warm and doesn't restrict your movements.

4F men's fleece underwear is designed as a functional second layer, perfect for winter activities – from skiing to daily walks on colder days.

4FWarm technology supports thermal comfort by helping retain heat close to the body without overheating. It's a reliable solution when you need additional thermal protection.

The fleece material provides a soft and comfortable feel without stiffness or restricting movement. The stand-up collar with a zipper effectively protects the neck from cold and wind.

Flat seams minimize the risk of chafing, and the regular, hip-length cut ensures freedom of movement and a comfortable fit during activity.
