Canada's Source for Merino Base Layers
Soft, Breathable Warmth for Cold-Weather Kits
The Icebreaker Merino 200 Oasis Crew is a high-performance base layer built for hiking, snow sports, and everyday cold-weather use. Made from 100% merino wool, it regulates temperature, resists odour, and delivers no-itch comfort against the skin; even during multi-day wear.
Purpose-Built for Movement and Comfort
This long sleeve crew features gusseted underarms for mobility, offset shoulder seams to reduce pack rub, and flatlock stitching to minimize chafing. The drop-tail hem adds coverage during active movement, and the slim fit keeps bulk low for efficient layering under mid and outer shells.
Field-Ready Features and Natural Performance
Weighing just 217 g (size M), the Oasis Crew is part of Icebreaker’s 200-weight warmth system; ideal for cool to cold conditions. The superfine merino fibers (18.9 micron) offer a soft hand feel while maintaining durability and breathability. Whether you're skinning uphill, hiking through frost, or layering for daily wear, this top delivers reliable warmth without synthetics.
