Icebreaker Men Merino Blend Core Heavyweight LS Half Zip

The Merino Blend Core Heavyweight Long Sleeve Half Zip is a versatile, everyday base layer top for any activity in cold conditions. The shirt is made from a stretchy jersey blend of soft merino wool and natural TENCEL™ Lyocell, featuring a half zipper for easy on and off as well as quick temperature regulation. Offset seams with continuous flatlock stitching prevent chafing while you're on the move.

Inspired by nature, icebreaker harnesses the performance properties of natural fibers to provide an alternative to clothing made from petrochemical synthetic fibers. Merino wool is an annually renewable fiber that is naturally odor-resistant, keeps you cool when it’s hot, warm when it’s not, and allows your skin to breathe, ensuring you feel comfortable all day long.
