Iconic 200-weight merino base layer that does it all from winter laps to year-round missions.
The Icebreaker Merino 200 Oasis Long Sleeve Crew is a best-selling base layer made from 100% merino wool jersey, built to handle everything from cold days on the hill to cool hikes and travel. The 200-weight fabric offers a sweet spot of warmth and breathability, naturally managing temperature and odour so you can wear it day after day without feeling rank. Gusseted underarms, offset shoulder seams, and flatlock stitching keep it comfy under packs and bib straps, while the drop-tail hem adds a bit of extra coverage when you’re on the move. It’s a true quiver-of-one thermal top that layers easily under mid layers and shells, or runs solo on crisp shoulder-season days.
- 100% merino wool – 200-weight jersey delivers soft, itch-free warmth with excellent breathability and odour resistance.
