8oz fabric so it's a mid-weight pullover. These do an excellent job as one of your layers in colder weather or as outerwear over a t-shirt in merely cool weather. I find these keep you warmer than the zippered kind. I buy medium at my size of about 5'-9" and 155lbs, 42 jacket and 30" waist on my jeans. They're not baggy, not tight and the waistband just comes down over my belt.
So, I like my hoodies fitted on me and I decided to try the small in the black. I'm almost 5'8 and I'm about 160pds. I received my hoodie today and let me tell you.... It's friggin awesome. The sleeves fit perfectly and are not all shrunkin feeling. It came down low enough to cover my behind and was fitted nicely without suffocating me. Such great quality for a perfect price. I own hoodies that I have paid almost $100 for and this fits feels and overall is better. I'm getting 1 in every color and probably will be set for the whole winter!
