Icebreaker Hombre 200 Oasis Camiseta de manga corta cuello redondo primera capa - Gritstone Heather - XXL

On a crisp morning hike above the treeline, you need a base layer that works as hard as you do. The Icebreaker 200 Oasis Short Sleeve Crew is the original merino base layer, trusted by hikers, climbers, and everyday adventurers for its natural performance. Made from 100% pure New Zealand merino wool jersey with a fabric weight of 200 g/m², it offers the ideal balance of warmth, breathability, and next-to-skin softness. The slim fit hugs the body without restriction, while offset shoulder seams and flatlock stitching prevent chafing under pack straps. Merino wool naturally regulates temperature, wicks moisture, and resists odor, so you can wear it longer between washes. Whether as a standalone top in mild conditions or a foundation layer in colder weather, the Oasis crew delivers reliable comfort on every outing.
