Designed for those who don’t stop for anything, the Ronhill Hyperchill jacket will become your favourite cool-weather running partner. Arms, side panels and centre back feature Prism fabric with one-way moisture transfer and a jacquard honeycomb pattern to trap air and insulate the body. Front, upper and lower back feature super light Octa fabric that is made from a hollow fibre with 8 protrusions to help transfer moisture to transfer away from the body whilst keeping you dry and protected from the elements. The gaps between the protrusions also trap air for maximum thermal enhancement and minimum weight. This is the perfect jacket to help you push through cold dark trails throughout winter and beyond.
