Long miles under the cruel sun call for the MAAP Eclipse Pro Air Jersey 2. 0. This dependable jersey delivers the same optimal performance as its predecessor, but now with a couple upgrades--the improved bonded front hem reduces bulk, and the new warp-knit, carbon-yarn sleeves increase durability and comfort. As we pedal, the material's micro-perforations let air flow through to keep us cool, while the zipper's locking tab ensures our fit doesn't release on its own.
