The Altura Esker Dune Insulated Pertex Women's MTB Cycling Jacket is a hybrid piece that delivers warmth to key areas such as the arms, lungs and kidneys using a combination recycled Pertex Quantum Eco outer windproof fabric and recycled insulation made from post-consumer PET. There is plenty of thermal warmth for the rest of the body from the brushed back softshell fabric which also provides advanced breathability through its technical knit construction. The baffled construction provides articulation through the arms and waist for greater freedom of movement on the bike. A snug, insulated and elasticated hood and shaped cuffs help to keep the drafts at bay making this ideal for those cooler days on the trails and a DWR coating will help to keep you dry for longer.
