Icebreaker Merino 260 Tech Long Sleeve Half Zip

Warm 260-weight merino half zip that locks in heat but still breathes on full-noise winter missions.

The Icebreaker Merino 260 Tech Long Sleeve Half Zip is a midweight base layer built for proper cold-weather riding, touring, and hiking. Made from 100% merino wool jersey, it delivers serious warmth while still breathing well and fighting odour on long days or multi-day trips. The half zip neckline lets you dump heat quickly on the climb, then zip back up when you’re sitting on a chilly chairlift. With gusseted underarms, offset shoulder and side seams, flatlock stitching, and a drop-tail hem, it’s designed to sit comfortably under packs and shells without rubbing or riding up.

• Warm 260 merino wool – Heavyweight 100% merino jersey fabric insulates, breathes, and naturally resists odour.
• Half zip ventilation – Zip neck collar gives easy temp control from frosty lift rides to sweaty hikes.
• Movement-friendly fit – Slim cut with gusseted underarms moves freely for touring, snowshoeing, or scrambling.
• Pack-ready seams – Offset shoulder and forward side seams plus flatlock stitching help prevent chafe under a pack.
• Drop tail hem – Extended back hem keeps your lower back covered when you’re bending, skinning, or strapping in.
• Winter layering staple – Ideal as a go-to midweight base layer for skiing, snowboarding, and all cold-weather missions.
