To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I like this jacket, it's perfect for winter running, or as an added layer under coats. It's fitted, with a little stretch, but not a lot. I'm 5'5" 130lbs with a 33 inch bust, and the small is tight. Not too tight, but fits like the picture. The zipper is high quality but a bit stiff so it ripples outward a lot if I'm sitting or bending. The pockets are warm and have zippers. The only thing I'd add is a hand warmer type sleeve. But otherwise a great piece for cold weather.
