The CP 2. 0 3 Season Light Jacket excels in autumn, winter and spring thanks to the use of technical fabrics that are able to trap body heat but at the same time allow for a high level of sweat evaporation. This creates a stable micro-climate inside so instead of overheating and then chilling from sweat build-up you get dry and comfortable warmth across a wide range of temperatures and intensity levels. The CP 2. 0 jacket also benefits from Ale's J-Stability System in the waist hem and semicircular fleece insert on the collar that both create snug and sleek closures that seal out the cold.

Attention is also given to riders who train after dark, with reflective inserts on the back of the jacket increasing visibility as you ride.
