Description

Perfect For Whatever Winter Dishes Out.

We are well aware of the additional hardships and discomfort associated with riding during the winter months. We certainly don't want our apparel to be our excuse for not getting out so if you are in the market for a thermal jacket that offers excellent protection during times of precipitation, take a look at the Women's Alpha ROS Jacket from Castelli. Part of the reason dressing for winter riding is so difficult is that we need to stay warm for most of the ride but if the pace picks up or there is climbing involved, we'll quickly turn into a sweaty mess leaving our muscles feeling stiff and us shivering for the rest of the ride. Castelli learned from working with pros and from other garments they created, that a softshell jacket with thermal, as well as wind- and water protection, was necessary and they sought out to create this garment. The Alpha ROS is prepared to pamper you with warmth and dryness this winter riding season.

Castelli uses the requisite Windstopper membrane in the 150 variety and thermal insulation in the Alpha, but does so in two detached layers allowing each piece to do what it does best and further regulate temperatures while climbing. As you heat up, unzipping the shell lets the wind hit the jacket's thermal layer cooling you off gradually and not an arctic blast to your base layer or chest. The thermal layer insulates while breathing quite well so you get more of a thermostat and less of an on/off feel. It's able to manage moisture continuously as you summit the climb keeping you dry as possible. At the top, simply zip up and head down without teeth rattling or finger clinching descending.

On the plunge down, you'll appreciate the Gore Windstopper 150 membrane. The windproof three-layer, four-way stretch knit fabric with a water-resistant DWR coating keeps wind out and precipitation at bay. You'll want this jacket just as much on solo base mile rides through the valleys as you will on tempo group rides over rolling terrain. Ride in comfort with the ventilating back panels resist trapping heat.

The Alpha ROS has more of an aggressive race fit reminiscent of a jersey than a jacket, and it leaves just enough room for a base layer underneath, which is all you'll really need since the thermal layer does such a wonderful job of providing warmth. Castelli cuts the jacket to accommodate your arms, chest, and shoulders while you're in a riding position with the only disadvantage is it may feel tight across the chest when you're off the bike.

The Alpha ROS features raw-edge construction at both the waist and wrists. This provides more freedom of movement than elastic bands or cuffs allowing the sleeves to integrate cleanly with gloves without bunching fabric, and a hem that stays put. The waistbands feature silicone grippers that moves with you, maintaining coverage as you ride. Keeping your neck happy is the collar engineered not to create a wind chute behind your neck while you're in the saddle. You'll have three jersey-style rear pockets for easy access to nutrition mid-ride, as well as a zippered front pocket to keep your valuables safe.

  • A race cut cycling jacket for the heart of winter
  • Windstopper 150 membrane shields against the elements
  • Maintains breathability and stretch for comfort
  • Outer and thermal layers unzip separately
  • Flat, raw cut hem and cuffs reduce bulk and lie flat
  • Three pockets supplemented by a zippered side pocket
  • Race fit is sleek with just enough room for a base layer
  • Recommended for temperatures hovering aroud freezing
