Icebreaker 200 Oasis Merino LS Half Zipper

With Bodyfit™ technology, the Icebreaker 200 Oasis Merino LS Half Zipper Base Layer is perfect for layering before you head out on any adventure, with its ability to thermo-regulate, keeping you comfortable and fresh when the temperatures are slightly warmer as well as insulating you in the cold. If too warm, simply un-zipper the neck for a fresh burst of ventilation. Merino wool is also exceptional at removing moisture from the skin as it forms and provides odor-resistance, which is great for longer pursuits. Plus, because it was made in the mountains rather than in a petrochemical laboratory, this Merino wool fiber is naturally renewable, recyclable and biodegradable* (*wool tops, under certain conditions).

When moving on the trail, you'll be moving freely thanks to flatlock seams that prevent chafing, alongside underarm gussets that add a touch of comfort and mobility.
