Why We Like The Alpha RoS 2 Light Jacket

Be seen in brilliant orange contrast through dark, wintery mist and rain showers with the Castelli Alpha RoS 2 Light Jacket. The lightweight shell protects you from irritating transitional weather as you roll towards summer. With honor, it inherits all the winning qualities of the Alpha RoS 2, but in a more breathable, lightweight design. GORE-TEX on the front and sleeves shields your torso from misty rain and chilled wind, while the lighter insulating layer of the RoS 2 Light manages to keep you comfortable in on hard-hitting training rides as body-heat builds. Nano Flex Xtra Dry on the back adds a thin barrier that repels rain while promoting additional heat loss and sweat evaporation.

The extremely versatile shell begs to be so much more as the three rear pockets provide ample room for valuables and snacks. The semi-fitting cut allows room for your favorite baselayer or training jersey without a sacrificing range of motion or freedom.
