I work in an office that can get quite cool--especially when sitting under the air conditioner. I was looking for a light sweater that wouldn't feel bulky over a dress shirt that would offset that--this works nicely.
It's definitely not bulky--it's only a little heavier than some of my waffle weave henley shirts. It's not baggy--especially in the arms. Not too tight but the fit is more like a shirt than a bulky sweater. It's VERY warm.
If you're over air conditioned or working in one of those spots near the door that's constantly opening in the middle of winter, I think you'll like this sweater a lot.
