The great thing about Nukeproof's Merino Long Sleeve Baselayer is its ability to perform across a wide range of temperatures and conditions. When it's cold it's a great insulator, and yet it's naturally breathable and odor resistant too; moisture quickly evaporates when the fibers can’t hold any more, helping you maintain your temperature and avoid overheating when riding hard. Nukeproof give the base layer a crew neck and raglan sleeve construction with flatlock seams for extra comfort and you'll find thumbholes at the cuff to seal in the warmth. With a looser mountain bike style fit you'll also love the freedom of movement it gives under your MTB kit.
