Icebreaker Merino 260 Tech Long Sleeve Crew

Heavyweight merino crew that keeps you properly warm and comfy when winter really settles in.

The Icebreaker Merino 260 Tech Long Sleeve Crew is a go-to heavyweight base layer for cold missions, from storm days on the hill to frosty pre-dawn starts. Built from 100% merino wool jersey in a midweight 260 fabric, it traps warmth, breathes well on the climb and naturally fights odour so you can wear it day after day. A slim fit hugs close to the body for efficient layering, while underarm gussets, forward side seams and offset shoulder seams keep you moving freely and help prevent pack rub. Finished with flatlock seams and a drop-tail hem for extra coverage, it’s a no-fuss, workhorse thermal top that slots sweet as into any winter layering system.

• 100% merino wool jersey for soft next-to-skin comfort, natural odour resistance and reliable winter warmth.
• 260 midweight fabric adds extra insulation over lighter thermals, ideal for skiing, snowshoeing and other cold-weather missions.
• Slim baselayer fit sits close to the body for efficient layering without bunching under mid layers or shells.
• Gusseted underarms and offset seams boost mobility and help prevent chafing when you’re wearing a pack or moving hard.
• Flatlock stitching throughout reduces rub points so it stays comfy on long days out or multi-day trips.
• Drop-tail hem design adds extra coverage at the back to keep draughts out when you’re bending, hiking or strapping in.
