{"product_id":"mens-100-merino-wool-thermal-base-layer","title":"Men's 100% Merino Wool Thermal Base Layer","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cem\u003eThe base layer that works harder than anything synthetic can.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eSynthetic base layers have their place but they cannot do what merino wool does. Merino naturally regulates temperature in a way that synthetic fibres cannot replicate — warm when you need it, breathable when you are working hard, never leaving you in that clammy overheated state that synthetic thermals produce the moment you start climbing. Natural antimicrobial properties resist odour at a level that means you can wear it across multiple days on the trail without it becoming a problem — a genuine advantage on multi-day hiking trips, ski holidays and extended travel where laundry access is limited. Midweight construction sits in the ideal position for autumn, winter and cool spring layering — substantial enough to provide real insulation as a standalone or first layer but slim enough to fit comfortably under a fleece or jacket without creating bulk. Soft non-itch merino knit with a crew neck and tagless construction means it sits comfortably against skin all day without irritation. Quick-drying and moisture-wicking for active use. Wash on a cold gentle cycle with wool detergent and lay flat to dry to maintain the fabric quality over time. Available in Black, Dark Grey, Light Grey, Navy and Purple in sizes S to XXL.\u003c\/p\u003e","brand":"Next Horizon gear","offers":[{"title":"Purple \/ S","offer_id":51638924542230,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Purple \/ M","offer_id":51638924574998,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Purple \/ L","offer_id":51638924607766,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Purple \/ XL","offer_id":51638924640534,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Purple \/ 2XL","offer_id":51638924673302,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Navy \/ S","offer_id":51638924706070,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Navy \/ M","offer_id":51638924738838,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Navy \/ L","offer_id":51638924771606,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Navy \/ XL","offer_id":51638924804374,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Navy \/ 2XL","offer_id":51638924837142,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Black \/ S","offer_id":51638924869910,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Black \/ M","offer_id":51638924902678,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Black \/ L","offer_id":51638924935446,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Black \/ XL","offer_id":51638924968214,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 2XL","offer_id":51638925000982,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Light Grey \/ S","offer_id":51638925033750,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Light Grey \/ M","offer_id":51638925066518,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Light Grey \/ L","offer_id":51638925099286,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Light Grey \/ XL","offer_id":51638925132054,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Light Grey \/ 2XL","offer_id":51638925164822,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Dark Grey \/ S","offer_id":51638925197590,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Dark Grey \/ M","offer_id":51638925230358,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Dark Grey \/ L","offer_id":51638925263126,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Dark Grey \/ XL","offer_id":51638925295894,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Dark Grey \/ 2XL","offer_id":51638925328662,"sku":null,"price":69.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/3563\/4198\/files\/mensthermaltop_4.png?v=1785671920","url":"https:\/\/nexthorizongear.com\/products\/mens-100-merino-wool-thermal-base-layer","provider":"Next Horizon Gear","version":"1.0","type":"link"}
