The Oasis Bodyfit Long Sleeve Crewe base layers represent quality & superior performance. The 200g/m² pure merino jersey-knit fabric has a smooth next to skin fell that is non-itchy for unparalleled comfort. Icebreaker are one of only a few companies in the world that use the best quality, super fine merino fibers in their garments & the jersey-knit construction is more dense & more durable than the Everyday rib-kit range from; this quality is reflected in the price, however the Oasis range is harder wearing. When you are warm the wool transports moisture away from the skin & the evaporation of this moisture helps to cool you down; however the merino fibres also contain millions of tiny air pockets that retain body heat to maintain you body temperature when the weather turns cold. Merino wool is naturally odour resistant because bacteria find it hard to hold onto the surface of the merino fibres, therefore it cant sit & multiply to create bad smells. This top is great on multi-day trips as you dont have to pack as many clothes; this is due to the fact that you can wear them for quite a few of days at a time without them getting smelly. Great for active use or everyday wearing. Close fit Great for snow sports, outdoors, hiking, travel & lifestyle Lightweight Naturally odour-resistant Breathable Offset shoulder seams to prevent pack rub Set-in sleeves for wide range of motion Anti-chafe seams for comfort Drop-tail hem for added coverage
