Comfortable, medium weight. Not too thick, not thin. Great for when you need a little extra warmth in the late summer, fall or light winter days. Roomy, does NOT have raglan sleeves (which can cut into you and look bad, feel uncomfortable). I've been wearing Russell clothing for many years. Rarely do they disappoint.

I purchased the 2X for a 345 pound, tall man. Fits a little snug at the very bottom but the sleeves are definitely long enough (even after washing) and the chest and stomach area are roomy. If you are over 350 pounds I would go with the 3X.

The only down side to these is that they will pill after 6-12 months of weekly washings. But if you turn them inside out before washing and don't wash with hard cloths like jeans, they will last longer and look nicer over time.
