The Sweet Protection Crossfire Merino Short-Sleeve Jersey combines the performance you expect out of a high-end road jersey with the natural benefits of Merino wool, thanks to a hybrid construction that uses synthetic materials in key areas to improve durability and longevity. Being nature's own technical fiber, Merino wool insulates when it s cold, yet remains breathable during high-intensity riding when the temps are warmer, making this a versatile piece to carry you all the way from spring through to fall. The jersey features gripper areas inside the sleeve openings and lower back to ensure a stay-put fit as you ride, as well as three spacious rear pockets and one zip pocket reachable from the side, allowing easy access to all your ride essentials.
