Icebreaker Oasis Crewe

Wrap yourself in the natural comfort of the Icebreaker Oasis Crewe, a long-sleeve base layer crafted from 100% merino wool. The fine jersey knit feels soft against the skin, while merino's inherent breathability and temperature-regulating properties keep you comfortable from cold mountain starts to high-output descents. Naturally odor-resistant, it stays fresher for longer, making it an easy choice for multi-day adventures.

The Oasis Crewe is built for motion: gusseted sleeves provide full range of movement, flatlock seams reduce chafing, and a drop-tail hem adds extra coverage when you bend and stretch. It layers neatly under a midlayer or shell for alpine skiing, ski touring and cross-country days, and works just as well on cool-weather runs and hikes. Wherever your itinerary leads, this top delivers dependable, next-to-skin performance.
