The merino and merino-blend t-shirts are made with a special featherweight design that enhances the cooling benefits of the wool. As a result, these tees are extremely soft and wick away moisture keeping you dry, cool and comfortable. You’ll find that these t-shirts have an ergonomic design that stretches with your movement while retaining an athletic and flattering fit. There are flatlock seams that minimise chafing and raglan cuts eliminates backpack straps from rubbing. In warm weather, merino wool traps sweat odours within the fibres and requires less washing. Icebreaker state that you can wear one t-shirt for seven days before you need to change and wash it. A by-product of less washing and the use of natural fibres is fewer resources down the drain and less plastic pollution washed into the oceans.
