{"type":"firestarter.listing","listing":{"id":"lst_1COkeybR","product_name":"Women's Wool Thermo Zip Polo by Brynje","category":"Baselayers","description":"Ships in 1-2 business days | Based in Norway | Est. 1887\nLightweight moisture management for high-intensity cold weather activities\nBrynje's Wool Thermo Zip Polo Shirt has a 3/4 neck with a ½ ventilation zip, solid-knit wool in front &amp; over shoulders, long raglan style sleeves for optimal arm mobility and non-chafing flatlock seams. An open-weave \"fishnet\" construction means perspiration vapor can be rapidly transported to the outer layers and dry faster than a solid knit construction. The Merino wool and polyester blend provides excellent warmth when damp and superior odor attenuation. The solid knit inlay provides a comfort layer under pack straps and to the chest area.  \nBrynje’s Merino wool blend is very soft against the skin and has greater strength and durability than 100% Merino wool yarns. Merino wool’s great odor management properties mean more uses between washings, which protects both the garment and the environment.  Brynje Wool Thermo garments are exceptional for warm weather use as well because of the thermostatic qualities of the mesh. \nFit: \nMesh base layers are generally quite stretchy in all directions and are cut long. As the girth increases the length will decrease. Generally, the Women’s sizes will be one size smaller than Unisex. For example, a Unisex S is equivalent to a Women’s M.\n_______________________________________\nSizing:\n\n\n\n Size\nHeight\nWaist\nChest\n\n\nX-Small\n\n4'9\" - 5' | \n1.45m - 1.5m \n\n\n25\" - 27\" |\n63.5 - 68.6cm\n\n\n28\" - 32\" |\n71.1 - 81.3cm\n\n\n\nSmall\n\n5'1\" - 5'3\" |\n1.5m - 1.6m\n\n\n27\" - 29\" | \n68.6 - 73.7cm \n\n\n33\" - 36\" |\n83.8 - 91.4cm \n\n\n\nMedium\n\n5'4\" - 5'6\" | \n1.6m - 1.68m\n\n\n29\" - 31\" |\n73.7 - 78.7cm \n\n\n37\" - 39\" |\n94 - 99cm\n\n\n\nLarge\n\n5'7\" - 5'9\" |\n1.7m - 1.75m\n\n\n32\" - 34\" | \n81.3 - 86.4cm \n\n\n40\" - 42\" |\n101.6 - 106.7cm\n\n\n\nX-Large\n\n5'10\" - 6' |\n1.78m - 1.8m\n\n\n35\" - 37\" |\n88.9 - 94cm \n\n\n42\" - 44\" |\n106.7 - 111.8cm\n\n\n\nXX-Large\n\n6'1\" - 6'3\" |\n1.85m - 1.9m\n\n\n38\" - 40\" |\n96.5 - 101.6cm\n\n\n45\" - 48\" |\n114.3 - 121.9cm \n\n\n\n\n\nWeight: 4.9 oz |","images":["https://cdn.shopify.com/s/files/1/0537/1177/files/Women_s_Wool_Thermo_Zip_Polo_by_Brynje.png?v=1741721559","https://cdn.shopify.com/s/files/1/0537/1177/files/Women_sWoolThermoZipPolobyBrynjeside.png?v=1741721559"],"price":124.95,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:43.868Z"},"share_url":"https://firestarter.network/l/lst_1COkeybR","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
