Icebreaker MER 200 ZONEKNIT LS HALF ZIP

The Mer 200 Zoneknit LS Half Zip is a high-weight merino base layer built for cold-weather performance. Spun from 100% Merino wool, it combines natural softness with reliable temperature regulation, making it an ideal first layer for intense winter exertion. The slim, close-fitting cut follows the body without restriction, while raglan sleeves and underarm gussets deliver generous freedom of movement.
