Heavier-weight merino crew that keeps you properly toasty through mid-winter missions.

The Icebreaker Womens Merino 260 Tech Long Sleeve Crew is a warm, midweight base layer made from 100% merino wool, designed for the coldest months of the year. A step up from the classic 200 Oasis, it delivers extra insulation while still breathing well and resisting odour, making it ideal under your shell for skiing, snowshoeing, or frosty hikes. The slim fit, gusseted underarms, and offset shoulder and side seams keep it comfortable under packs and bib straps with minimal chafe. It’s a true winter staple that pulls double duty as a cosy everyday top when the temperature really drops.

• 100% merino wool – 260-weight jersey fabric offers serious warmth with soft, breathable next-to-skin comfort.
• Winter-focused base layer – Designed as a warmer version of the Oasis for skiing, snowshoeing, and cold-weather trips.
• Movement-friendly cut – Gusseted underarms and slim fit allow easy layering without restricting your range of motion.
• Low-friction seams – Offset shoulder and backward-set side seams plus flatlock stitching help prevent pack rub.
• All-day comfort – Natural merino fibres manage moisture and odour, so you can wear it multiple days in a row.
• Layering ready – Streamlined crew-neck design fits cleanly under mid layers and jackets for low-bulk warmth.
