{"product_id":"heavyweight-tanana-womens-crew-100-merino-wool","title":"Women's Tanana Heavyweight 100% Merino Wool Crew Base Layer","description":"\u003cp\u003eNamed after Alaska's Tanana River—an important tributary of the Yukon that flows past Fairbanks—this heavyweight crew is built for arctic temps. The 400 g\/m² interlock knit wraps you in a blanket of warmth while the superfine 18.5-micron merino stays soft and itch-free against your skin. When cold weather tries to keep you indoors, this is how you fight back.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy You'll Love This Top:\u003c\/strong\u003e At 100% Australian merino wool with no synthetic fillers, this delivers pure natural warmth. Princess seams create a flattering, shaped silhouette that moves with your body instead of hanging like a box. The tagless label eliminates itchy neck irritation, while flatlock seams prevent chafing during all-day wear. Works as a base layer under shells and jackets, or as a cozy mid layer on moderately cold days.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy Merino?\u003c\/strong\u003e Heavyweight merino is your coldest-weather workhorse. Unlike synthetic base layers that trap odor and feel clammy, merino actively manages moisture and neutralizes bacteria. Wear this top multiple days without washing—it'll stay fresh while synthetics get funky. The natural temperature regulation keeps you comfortable whether you're generating heat snowshoeing or sitting still ice fishing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSize \u0026amp; Fit:\u003c\/strong\u003e Regular fit with room to breathe—runs true to size. 100% Merino Wool, 400 g\/m² heavyweight interlock knit, 18.5 micron fibers.
