Born of the close-fitting thermal fabric, these stretchable Duo winter jerseys ensure comfortable breathability. Their Italian Roubaix clothing keeps the torso from the numbing cold. The wind-proofing fabric prevents the chilly air from seeping in. Water-resistance has been added to keep the rider dry while pedaling. The full length zipper design armors the rider against the chill by closing up to the top. Three back rear pockets allow the rider to organize his storage while the zipped pocket stores the valuables. Reflectors are included on the front, back and side arms for the safe nighttime cycling. For efficient skin-fitting, ergonomic design has been included. Silicon grippers at the waist hem keep the jersey from riding up which normally causes issues.
