Description

Embrace the unpredictable.

Your cycling wardrobe likely consists of wet-weather gear and dry-weather gear, with little overlap. Until recently, those really were the only options, with wet-weather gear that would leave you feeling bogged down and steamy when you get pedaling, and dry gear that just couldn't hold up to more than a couple of raindrops. Castelli created the Gabba and Perfetto to help cover the bases for both, but the release of the Alpha ROS Jacket takes things to the next level. With limited edition colors, this model of the Alpha ROS Jacket captures the performance we expect from Castelli, along with an exceptionally stylish and elegant aesthetic.

The Alpha ROS Jacket is ready for rain or shine, with its two-layer construction that separates thermal insulation from wind and waterproof shell. The front offers a double-opening so you can ventilate without exposing yourself directly to the frosty chill. With two-layer construction, Castelli enables each layer to do their job to a higher degree, so Windstopper can keep its focus on sealing out water and wind, keeping the thermal layer dry so it can excel at regulating temperatures. The inner layer provides thermal warmth that wicks away perspiration and allows heat dissipation when needed, so your core temperature can be regulated and you're able to put down the power on long climbs without overheating.

Shielding you from the elements, Gore's Windstopper membrane is reinforced with YKK Vislon waterproof zippers and selective seam sealing. By being selective with seam-sealing, Castelli is able to maintain great dry-weather riding qualities on the Alpha ROS Jacket, without compromising water protection. Castelli won't make the claim that the jacket is 100% waterproof, but it does present the jacket with confidence to stand up to most cold and wet riding with resilience.

With a form-fitting cut that's much like a jersey, the jacket leaves little room for drafts or excessive fabric that flaps in the wind behind you. The cut is designed for in-saddle comfort, so you might notice the chest feels a bit tighter than normal across the chest when off the bike; however, on the bike the design is built to accommodate your arms, shoulders, and back when you are in the drops, eliminating extra fabric in that position. Since the design already features 2-layers you often won't need more than a baselayer to remove the chill, depending on the day's weather and your own preference. The jacket can span temperatures ranging from 23-to-50 degrees Fahrenheit, but—again—that depends on how hot your engine runs.

  • Pedal on through wind and rain in this cycling jacket
  • Limited edition colorway stands out in a crowd
  • Blocks wind and water with Windstopper 150 membrane
  • Insulating midlayer unzips separately for heat dumps on climbs
  • Race fit eliminates excess material and cold air drafts
  • Breathes and wicks away sweat on long climbs
  • Raw-cut hem and cuffs and comfort and improve fit
  • Castelli's revolutionary all-weather race kit continues to evolve
