I've used this jacket for several weeks in late fall weather ranging from the high 40's to mid-60's. I typically just wear a tee shirt underneath. It provides just the right amount of warmth for a vigorous ride. The construction is high quality, and I've washed it several times with no issues. I like the high zip-up collar on the jacket, particularly at the start of a ride on a cold, windy day. Probably the only thing I find lacking for a winter coat is that there is very little at the sleeves, other than some loose-fitting elastic to keep cold air from going up the sleeves. Some velcro straps, or something along those lines at the sleeves would be a good idea.
