Icebreaker 200 Oasis Half Zip Longsleeve

The 200 Oasis Half Zip Longsleeve is a merino wool baselayer built for cool-weather adventures. Its 100% merino construction offers comfortable everyday performance, while the half-zip design helps regulate ventilation when conditions or effort change.

Thoughtful shoulder seams reduce irritation beneath pack straps, and flatlock seams help prevent chafing. Underarm gussets support mobility and breathability, making it a dependable foundation for hiking, skiing and other active outdoor pursuits.
