When the cold weather is making you second guess going out for your run, the 2XU Women's Winter Ignition 1/4 Zip will put your mind at ease. The three-dimensional waffle construction has a double-knitted brushed interior that creates small air pockets to keep body heat in but also allows air to flow through the fabric to increase breathability and a quick-drying environment. The stand collar and flip-over mittens provide extra coverage when needed while the raglan sleeve and stretchy fabric give you freedom of movement and comfort.
