Design Philosophy An Endura staff favourite and a product that we are really excited to introduce into the range. Wear it as a stand alone riding jersey to take the chill of spring or autumn rides or as a mid-layer during the colder winter months. Going by the riders at Endura HQ, you won\'t want to take it off. Fabric Grid backed fleece has long been used in the outdoor industry, but is a new addition to the mountain biking world. It balances insulation and breathability, keeping you warm and sweat free for the duration of a ride.
