I have a feeling I'll be wearing this a ton this winter. I got a small and it fits great. I get a small in every shirt from Bonobos and they are consistent. This is a high quality sweater and it will go with anything. Dress it up with a tie or wear it with jeans. It's thick but still lightweight. Note that since it's lambswool it is a little scratchy if I wear short sleeves under it. I hope to grab one of the other colors soon.

I have the navy version and liked it so much that I went ahead and ordered the gray and green. Unfortunately the green does not match the color on the web site and the grey sweater arrived with a cuff seam already unraveling. I have always been a huge fan of Bonobos but it seems the quality on their sweaters is not on par with their pants. Still a fan but disappointed.

This is a really comfortable sweater. It fits well, and the sleeves are long enough for a taller guy.
