A quarter-zip is better. The ability to open the collar and dump heat when you are working hard on a long climb — and close it back up the moment you stop and the temperature drops — is one of those small functional details that makes a meaningful difference across a full day on the trail. This men's 100% merino wool quarter-zip base layer is built around that principle, combining the natural performance of 200GSM merino wool with a high collar and quarter-zip that gives you real temperature control without having to add or remove a layer. Merino wool at 200GSM sits in the ideal position for year-round use — lightweight enough to work as a standalone top in mild conditions and as a base layer under a fleece or jacket when temperatures drop seriously. Natural temperature regulation that adapts throughout the day without you thinking about it — warm when you need it, breathable when you are working hard. Moisture wicked away from the skin during active use so you stay dry rather than sitting in damp fabric after a long effort. Natural antimicrobial properties resist odour across multiple days of wear on extended trips where laundry is not an option. Fine merino fibres sit comfortably against bare skin all day without itch. Hand wash with wool-safe detergent — lay flat to dry, do not tumble dry. Available in Black, Grey and Green in sizes M to 2XL.\u003c\/p\u003e","brand":"Next Horizon gear","offers":[{"title":"Black \/ M","offer_id":51683596435734,"sku":null,"price":99.95,"currency_code":"GBP","in_stock":true},{"title":"Black \/ L","offer_id":51683596468502,"sku":null,"price":99.95,"currency_code":"GBP","in_stock":true},{"title":"Black \/ XL","offer_id":51683596501270,"sku":null,"price":99.95,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 2XL","offer_id":51683596534038,"sku":null,"price":99.95,"currency_code":"GBP","in_stock":true},{"title":"Green \/ M","offer_id":51683596566806,"sku":null,"price":99.95,"currency_code":"GBP","in_stock":true},{"title":"Green \/ L","offer_id":51683596599574,"sku":null,"price":99.95,"currency_code":"GBP","in_stock":true},{"title":"Green \/ XL","offer_id":51683596632342,"sku":null,"price":99.95,"currency_code":"GBP","in_stock":true},{"title":"Green \/ 2XL","offer_id":51683596665110,"sku":null,"price":99.95,"currency_code":"GBP","in_stock":true},{"title":"Grey \/ M","offer_id":51683596697878,"sku":null,"price":99.95,"currency_code":"GBP","in_stock":true},{"title":"Grey \/ L","offer_id":51683596730646,"sku":null,"price":99.95,"currency_code":"GBP","in_stock":true},{"title":"Grey \/ XL","offer_id":51683596763414,"sku":null,"price":99.95,"currency_code":"GBP","in_stock":true},{"title":"Grey \/ 2XL","offer_id":51683596796182,"sku":null,"price":99.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/3563\/4198\/files\/menslongsleevev3_3.png?v=1786271026","url":"https:\/\/nexthorizongear.com\/products\/mens-merino-wool-quarter-zip-base-layer","provider":"Next Horizon Gear","version":"1.0","type":"link"}
