Alpha RoS 2 Jacket

Blending into the deep green of the foggy winter forest is the Limited Edition Castelli Alpha RoS 2 Jacket in military green. If you aren’t easily swooned by indoor training during winter, the Alpha RoS 2 provides a feature-heavy barrier against nature’s bite, ensuring the miles are logged even in the harshest conditions. Continuing Castelli’s impeccable lineage of inclement weather, performance clothing, the Alpha RoS 2 gets a double-layered Alpha construction comprising an inner insulation layer and outer Gore-Tex Infinium wind and water barrier. The layers provide protection down to 23 degrees F as well as superior wind and water resistance to brace against pocket showers or a ride-long drencher.

Castelli manages to engineer subtle and effective traits into the Alpha RoS 2 that, at first glance go unnoticed, but act as welcomed finishing touches you’ll appreciate during mixed weather riding. Further adding to the comfort and warmth characteristics are the high neck, which prevents cold air rushing on the chest, and the double layer cuffs that seal out water and wind and allow for expert fitting under gloves. A water-resistant zipper and taped shoulder seams seal out areas that are prone to water ingress, while discreet back flaps vent out heat to maintain comfort on rides up to 50 degrees F and during intense interval sessions. Castelli adds drainage holes to the pockets, which provide an extra dose of security compared to the mesh openings of previous jackets, and a zipper side-pocket corrals valuables for the long haul.

Suprisingly fantastic!

I had the alpha ros (?) version from a year or two ago, and my expections were moderate for this jacket. I simply wanted an upgrade, the price was great and it appeared more streamlined. Turns out it is much improved, more aero, the green color is a nice change from the orange (I still use a rear taillight) and it fits more like an athletic cut. The first ride it was 25 degrees outside and I only had this jacket and a base layer and it was comfortable. For reference, I am 5'11" 195 lbs, waist 33 arm lenght 34", and muscular. I purchased the XL and it fits great. Highly recommended and the color is a welcome change!

I’ve used this jacket down to around 30 F both road and mountain biking. it’s kept me warm and comfortable with just a wool base layer underneath. For sizing I’m 5’10” and 150 lbs and the medium fit is spot on. Not too tight like my assos jackets but not at all loose or baggy. I wear a size medium top across multiple cycling brands. This is the first time I’ve tried castelli (most of my stuff is assos or Rapha), but I am very impressed.

Beautifully made jacket, seals you in from every angle to remain warm and toasty while feeling light and mobile. The wind rolls off this jacket, and you’ll feel faster immediately. Lightweight, flexible and tight fitting. It’s supposed to be snug and tight, it is shorter in the front so don’t be thinking you have the wrong size.

Jared, I size M but all my Castelli gear is XL. I am surprised the jacket fits you well in size L ?? I am 6', 170lbs, 40' chest . so you make me hesitating what size to order. Can you comment further on the fit?
