Warm without the bulk or weight
Quality materials, excellent fit & finish as expected with Giordana. The jacket does a good job of repelling light rain & blocking wind. Outer face fabric is abrasion resistant but has plenty of stretch. It is surprisingly warm considering how light & thin the jacket is, but I need additional under layer (sweater or hoodie) if temps dip below ~7 degrees C. I don’t consider this adequate protection by itself below ~4 C unless you’re generating plenty of body heat, but that’s me. It’s not entirely windproof & not waterproof, but is well-suited for hard workouts in chilly conditions. The fit is somewhat more relaxed but still form-fitting & not bulky or heavy. If you need to add a layer, however, size up. I normally wear a medium but large provides a snug fit with enough room for light layering.
Wore it on a 40 deg ride. Warm , windproof, . Just wore a baselayer underneath
In the low 30s at the start of my ride, the jacket with a long sleeve jersey kept me plenty warm for the 2.5 hours of the ride. Some wind. Fits true to size. Highly recommend it.
