The FUTURUM PROFORMANCE Base Layer is an essential for any cyclist’s wardrobe. It wicks away moisture and offers great breathability and warmth, so it is perfectly suited to colder and winter conditions. It is the perfect base layer to wear under a long-sleeved jersey and windvest or rain jacket or thermo jacket. In heavy rain, we would recommend using this long-sleeved base layer under our popular 4 SEASONS jacket. As it is round-knitted and offers 4-way stretch and a seamless design, it will ensure that you can ride in great comfort without the irritating pressure points that might hinder your performance.
