{"type":"firestarter.listing","listing":{"id":"lst_pnAFm75I","product_name":"Men's Super Thermo Boxer with Windcover by Brynje","category":"Underwear","description":"\nShips in 1-2 business days | Based in Norway | Est. 1887\nLightweight moisture management for high-intensity cold weather activities\nBrynje's Mens Super Thermo mesh boxer short provides insulation and breathability. 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 Polycolon® mesh provides 4 to 6 times the insulation value of solid knits while keeping moisture off the skin making it ideal for high and low-intensity activities in cold or wet weather. The wind panel keeps sensitive parts protected from wind.\nPolypropylene has a very high strength-to-weight ratio providing super light garments designed to withstand years of extreme use. Brynje Super Thermo garments are exceptional for warm weather use as well because of the thermostatic qualities of the mesh. \nFit: \nMesh baselayers are generally quite stretchy in all directions. As the girth increases, the length will decrease. This style is a Unisex fit. 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\n\n\nSmall\n\n5'4\" - 5'6\" |\n1.6m - 1.7m\n\n\n29\" - 31\" |\n73.7 - 78.7cm \n\n\n\nMedium\n\n5'7\" - 5'9\" |\n1.7m - 1.75m \n\n\n32\" - 34\" |\n81.3 -  86.4cm \n\n\n\nLarge\n\n5'10\" - 6' | \n1.75m - 1.8m\n\n\n35\" - 38\" |\n88.9 - 96.5cm\n\n\n\nX-Large\n\n6'1\" - 6'3\" |\n1.8m -1.9m \n\n\n39\" - 42\" |\n99.1 - 106.7cm\n\n\n\nXX-Large\n\n6'4\" - 6'6\" | \n1.9m - 2m\n\n\n43\" - 45\" | \n109.2 - 114.3cm\n\n\n\n3X-Large\n\n6'7\" - 6'9\" | \n2m - 2.1m\n\n\n46\" - 50\" | \n117 - 127cm\n\n\n\n\n\nWeight: 2.8oz | 80g (medium)\n*Weight may vary due to fabric variation \nMaterials:  \n\n100% Schoeller® Polycolon® synthetic yarn, knitted into a 3/8″ open weave mesh\nWindcover: 50% polyester and 50% polyurethane\nbluesign® certified fabric\nMaterial weight: net 140gsm\nPFAS-Free\n\nMade in Poland\n***Returns cannot be accepted on this product\n_______________________________________\nCa","images":["https://cdn.shopify.com/s/files/1/0537/1177/files/SuperThermoBoxerwithwindcoverbyBrynje.png?v=1737059707"],"price":59.95,"currency":"USD","in_stock":true,"inventory_qty":59994,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:43.877Z"},"share_url":"https://firestarter.network/l/lst_pnAFm75I","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
