The Icebreaker Vertex Leggings are a mid weight base layer trouser that is supremely soft & comfortable. They are made from a high performance 100% merino wool fabric that keeps you comfortable in all conditions. These trousers are non-itchy because Icebreaker are one of only a few companies in the world that use the best quality, super fine merino fibers. The jersey-knit is denser & more durable than the Everyday range that uses a rib-kit construction; this also leaves a smooth feeling finish which is great for next to skin comfort. In warm conditions this amazing fabric transports moisture away from the skin to be evaporated, keeping you cool & comfortable. Yet on the other h&, the super fine, soft wavy fibres contain millions of air pockets that lock in body heat to keep you warm in cold conditions. Truly an all year round, all conditions piece of kit. One of the best features of Icebreaker Merino Wool is its amazing ability to naturally resist odours. You can wear these trousers for many days before they starts to stink, making them perfect for multi day trips. The 260 g/m² fabric is suitable for colder climates; for example if you are of skiing in the alps or off to Scotland to do some winter mountaineering.
