Excellent product. Fits great and looks good. This will keep me warm on cold winter days. I have lost 24 pounds by dieting and walking, and I want to continue walking this winter. These thermos are perfect for me. Great price and fast and free delivery.

True to size. Love it's made with some cotton!

Happy these are more cotton than polyester, but it is a blend. I was concerned that a large black pair wouldn't be big enough for my older brother but I'd definitely say these are true to size as he is a large! These would've been wayyyy to big if I sized up. He complained the quality. These are a little thin, not for super extreme cold weather but will definitely help cold weather.
