Excellent cool weather jacket, with a slight let down
30/04/2023
Excellent cool weather jacket. Wore it on a 14c rainy morning and it kept me dry throughout the ride. I just had to unzip the top layer half way during the climbing efforts and any sweat buildup quickly evaporated, it really is very ventilated and comfortable. The only issue I had was with the side pocket zipper which snapped and broke off the first time I tried to use it. I wish Castelli put a better quality zipper on the side like the one in the front to make it a 5 start jacket. Also, sizing is perfect as per size chart - No need to upsize.

I invested in the ALPHA RoS 2 LIGHT JACKET this year to provide me the ability to ride more in the cold, winter months. Let's say before purchasing this jacket, I was a bit more selective on what days and temperatures I would or could comfortably ride in. This jacket has not disappointed me! It provides me with comfortable wind and thermal protection with added light rain protection.
Look and Feel: Quality and feel is great. The material has a smooth, quality feel to it, yet not heavy or bulky. Check sizing carefully as I normally wear a U.S. large, but bought the XL, and fits perfectly.
My use so far: I'll take my last ride as an example: Thirty plus mile ride. Weather was mid to upper 40s (Fahrenheit), partly cloudy. I wore a thermal jersey under the jacket. I was completely comfortable. Kept me warm and shielded from frontal wind and cold. Back provided plenty of ventilation. I have had previous colder rides and was quite comfortable with a thermal jersey underneath. The ability to zip/unzip outer layer and the inner vest-like layer is awesome. It works well to help regulate my temp especially when I'm pushing it or expending more power.
I like the added secure zipper pocket on the left side. I use this for valuables, keys etc. The zipper position is a bit tough to open and close due to its location on your side. Harder to open with winter gloves... I take my glove off to open or access the pocket. But having a secure spot for my valuables has been great.
Bonus - Visibility is quite important to me especially in winter when rides can be during darker times. I love the bright green color and the reflective elements on the jacket.
I hope this helps others decide if this is the jacket for them!
