The Ultraz Winter Booties from Assos offer fantastic weather protection for riders who keep going throughout the colder months. A 3-layer softshell construction with a PU bonded membrane ensures that the rain and road spray won’t penetrate the fabric, with a DWR treatment on the outside to prevent the material from wetting out. An offset camlock zip at the rear of the bootie helps when putting them on or taking them off and the sportGrip material on the bottom increases grip and durability when off the bike. As ever with Assos, performance is of the utmost importance, so the zeroCuff design smooths the transition between the bootie and the leg for better aerodynamics.
