200 Oasis LS Half Zip Mens

The Icebreaker Mens 200 Oasis LS Half Zip is a long-sleeved zip-up undershirt for men that, thanks to the warmth of the merino wool, works perfectly as a base layer during chilly outdoor adventures. Gussets under the sleeves allow full freedom of movement and the zipper at the collar also allows the shirt to breathe and regulate temperature, while the slightly longer back means your back stays warm, even when you bend forward.
