This Light Cycling Jacket Provides Heavy-Duty Protection From the Elements

Even though the weather outside is frightful, hop on the bike regardless because this light jacket is deliciously delightful. Cold weather is no match for the Castelli Women's Alpha RoS 2 Jacket. With unbelievable insulation, ventilation, and comfortable fit as well as the waterproof finish that also protects you from harsh winds, get the high-performance cycling equipment that you deserve without breaking the bank.

Constructed from GORE-TEX INFINIUM™ WINDSTOPPER® 150 wind fabric for its fantastic water-resistant qualities, and not to mention the incredible wind protection provided on the front and sleeves. Featuring a Nano Flex Xtra Dry composition on the back of the jacket for improved ventilation while rain is shed like nothing thanks to the state-of-the-art nanotechnology water repellent finish. Alpha double-layer makeup separates the ProSecco Strada insulating layer from the waterproof outer layer to keep you warm and dry. With a raw-edge waist design that lies flat and actually moves with you, never settle for an uncomfortable fit again.

Prepare for cold-weather months with style. The Castelli Women's Alpha RoS 2 Jacket not only manages to balance a great fit with the waterproof and wind-resistant design, but its double-layer construction allows you to customize the fit to your liking. Rediscover the joys of winter with this cycling jacket — staying warm and dry all season long.
