Ridiculously undersized. Get at least one size larger - mayby more.
On the plus side, there's an inner zippered chest pocket (not listed in description) besides the 3 outer pockets. The front hand pockets are lined with thin felt - great to absorb moisture. All pockets are zippered with pulls and the zippers are well-made.
All-in-all, this lightweight puffer sweater is one of the few around with all those pockets. Perfect to go under an outer weather-resistant shell for the spring rains.
If not for the silly size business, I'd give it 5-stars.
