At first I wasn't too sure about this jersey. It didn't fit as snug as I'm used to and the large reflective stripe across the chest is not generally my style. I now own three of them and it's my goto jersey during winter. The fleece is super soft on your skin, the jersey gives you room for a baselayer if you want, and the reflective stripes do their job making you visible. I pair this with a wind breaking layer down to 32F and wear it by itself from 45-60F. I find that I'm wearing my Castelli jackets less and less these days. Great for PNW commutes, which is why I own 3.
I wear this jersey for weekend warrior type riding. Riding during the winter in the East Coast can be challenging, but this jersey did a very good job. I have to wear a good base layer and I'm ready for a few hours in the saddle. The price was a deciding factor as well.
