260 Tech Long Sleeve Half Zip – Women's

When cold-weather efforts demand warmth without the suffocation, the 260 Tech Half Zip is our top pick for women who push hard in winter — trail running, skinning, or climbing. Midweight 260gsm merino with Corespun LYCRA construction regulates temp naturally and stretches with you, while zoned mesh panels and a half-zip collar let you manage heat on the fly.

• 260gsm midweight merino wool keeps you warm on cold starts without trapping heat during hard efforts — no synthetic insulation needed
• Corespun fabric blends merino with LYCRA for four-way stretch and added durability while preserving merino's natural next-to-skin feel
• Zoned body mapping with merino mesh panels targets ventilation at high-heat zones so you don't overheat mid-climb or mid-run
• Half-zip collar lets you dump heat fast; flatlock seams and offset shoulder seams eliminate chafe under a pack or harness
• Naturally odor-resistant merino stays fresh across multiple hard wears without chemical treatments — fewer wash cycles, more time outside
