Assos pioneered the use of layering, creating the ALS or Assos Layering System that has become the bedrock of their ranges. Delivering refined thermal and climate control, Assos' CLIMA system takes matters further, simplifying the choice for riders by breaking down their range into 4 distinct grous. Summer; Spring / Fall; Winter and All Year.
This quarter zip under-layer is the perfect warmth piece for cold days riding.
