Two things come to mind regarding the Castelli Prologo 3 sleeveless jersey - comfort and Castelli's iconic style. Castelli make the Prologo 3 sleeveless jersey with Stratus fabric that feels at home next to the skin. The sleeves and bottom hem have a light elastic for a snug but very comfortable fit. The Prologo 3 features ingenious technology like reversed arch pockets to prevent pocket sag and Castelli's proprietary Stratus two-layer fabric that makes a base layer seem optional.
Dual layer Stratus fabric is a summer weight fabric engineered to pull moisture away from your skin. A Prosecco treatment helps to move moisture aggressively to the surface for quick evaporation. A fine mesh panel in the center of the back creates a little more airflow exactly where heat can build up and also adds a bit of stretch to the jersey. A new full zipper provides maximum venting options.
The back has a scorpion logo over the center pocket. Three large pockets provide plenty of utility. A zippered pocket on the side of the right rear pocket is great place to store valuable items like keys, credit cards or cash.
