I've worn this jacket several times, and find it terrific for temps down to about 50f while wearing only a thin baselayer underneath. I bet it would be fine for lower temps when wearing something more substantial underneath (note - I have the Alpha RoS 2 jacket for temps below 50f, however, I'd have no reservation riding with this jacket, and something thicker than a baselayer underneath with temps into the 40s, and maybe upper 30s ). The jacket is race cut, and I sized up one size to get a super fit. The fit feels great when on the bike. The pockets are reasonably deep, have ample room, and snap to the body for keeping things secure -- no issues holding stuff, and easy to get stuff in, and out. I've been in light rain with it only one time, and I my upper body remained absolutely dry. The fabric feels great to the touch, and breathes well. Overall, I am impressed with this jacket (and the Alpha RoS 2 as well.)
This is an excellent all-weather jacket for those cooler and even wet days. The jacket is well built, lightweight and does a great job. I don't live in the freezing north, but this is my go to for the few cold days we get here. My only complaint is the sizing chart is a joke. Based on my measurements, I could get away with a large, but in the end needed XX large. The cut on this jacket is very small, so order a size or two up. I would give it 5 stars but knock one off due to the small sizing.
I love this jacket, it is perfect for spring and fall days riding. With a thermal base layer the functionality is even broader.
Like all things Castelli, they run small (by American Standards)....so size up...!!!
Received my jacket and this is a race fit. Very happy with a baselayer or over a jersey. The build quality is fantastic, the Neoshell material stretches and it has pockets in the back. Looking forward to many miles wearing this.
