I'm 5'8" 170ish pounds, and a large fit me perfectly. I really like the quality and warmth of the material. I'm currently wearing this for the fall season in Albuquerque. We typically see lows among the 30s and 40s and this is warm enough to wear during the evening.

The XL size ordered fits well and wears well. I like the color and for cooler weather, this shirt will accommodate a light weight 1/4 zip thermal underneath for added warmth. Zero shrinkage if allowed to air dry or use low heat in dryer. Although I would've expected a slightly heavier material for a "heavy weight" shirt, I would consider buying additional shirts of this manufacture.

Loved the weight and feel of this shirt so much I ordered another one. This is without a doubt my favorite cold weather shirt.

I bought 2 of these shirts size medium. 5'10" 135lbs. The shoulders and sleeves fit perfectly. The body is huge. They are absolutely my favorite shirt, nice colors, substantial fabric, super comfortable, and they don't attract dog hair (unlike any other fleece shirt I own). I just ordered a small one to see if the body will be trimmer. I suspect the sleeves will be short. If so I will roll them up. The label shows 2 sizes US and ASIAN at first I thought they sent me a large. Poor eyesight. CS was very helpful in explaining this.
