Enjoy lightweight thermal protection in this half zip base layer made from the revolutionary performance fabric Meryl® Nexten, an extremely light hollow fibre. The core of the fibre traps air which can contribute to increased thermo-insulative properties. The result is a fabric that keeps the wearer warm with a third less weight. As well as being windproof this top also has added stretch for a comfortable fit and seamless knitting. The fabric is quick drying and provides exceptional comfort during any athletic activity.
