Very snug in the arms as if made for someone without muscles. Also wide around neck/collar area. Also you aren't buying a cardigan hoody. You're buying a pull over hoody that has a cardigan "design" achieved by having buttons sewed on. The white shirt that appears to be just a layer under the cardigan that you think you're buying is really a piece of clothe stiched in at chest area and bottom rim. Not as expected. Ok product but not what I thought I was buying.
