This pullover is the most useful addition to my running clothes connection for all season. In the spring and fall in particular, it does great in misty/foggy/drizzly weather; in the winter, it can handle snow flurries; and in the summer, it's a great warmup layer before your workout. It's a flattering cut and not bulky at all. Love the zip pockets - very functional. I found it ran a little small - I typically wear an XS-S, and while the XS fits I think sizing up would've been better to allow me to wear more layers underneath.
