Husband approved pullover sweater
Color: Navy Blue, Size: X-Large
Nice warm men’s stylish sweater. Fit my husband well. Pull over is cozy casual. He says it’s a good weight for warmth and moth itchy… and that’s something to say as he doesn’t usually like sweaters!

Super tight
I'm 6'1 250. Muscular build. I can normally wear XXL, sometimes order 3XL to be safe when ordering from Amazon. These 3XL are super skin tight. Nowhere near a "normal" 2XL, let alone a 3XL.
