The Icebreaker Tech T Lite is made from soft jersey-knit 100% pure Merino wool. This top is 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 this top for many days before it starts to stink, making it perfect for multi day trips as you will only need to take one base layer. The 150 g/m² fabric is suitable for year round use & this Tee shirt is perfect base layer to be worn next to the skin under other layers, or as a st&-alone fine weather travel & leisure T Shirt.
