200 Zone Long Sleeve Base Layer – Women's

Built for high-output days when you're moving hard and stopping often, the 200 Zone is our top pick for women who need a merino base layer that actually keeps up. BodyfitZONE construction pairs lightweight merino jersey with mesh panels in the high-sweat zones, so heat dumps fast and you don't overheat on the climbs. Flatlock seams mean zero chafe, even on long days.

• BodyfitZONE construction combines merino jersey with strategically placed mesh panels to push heat and moisture out where you need it most
• 200-weight merino wool regulates temperature naturally — warm when you stop, breathable when you're grinding
• Lycra blend adds stretch and mobility so the fit moves with you, not against you
• Flatlock stitching eliminates seam friction during repetitive motion — great for long trail runs, ski tours, or big hiking days
• Available in Black/Mineral colorway — a versatile two-tone that works as a standalone layer or under a shell
