Intraknit Active Base Layer Crew – Women's

Built for high-output cold-weather efforts on the trail or in the mountains, the Intraknit Active Crew is our top merino base layer pick for women who run or move hard in the cold. Body-mapped Intraknit construction puts stretch and ventilation exactly where you need it, so you stay regulated without overheating under a shell. Merino's natural odor resistance makes it a reliable choice for multi-day adventures.

• Body-mapped Intraknit zones deliver targeted ventilation and stretch where your body generates the most heat and needs the most movement
• Merino wool blend wicks moisture, dries quickly, and resists odor through extended hard efforts and multi-day use
• Low-seam construction minimizes chafe and irritation against skin during high-output activity under a pack or layers
• Slim, athletic fit layers cleanly under a mid-layer or shell without bunching or adding bulk
• Available in Twilight Blue-Pool Blue — a versatile colorway that works as a standalone top or foundation piece in a layering system
