Review: Washes fantastic - Bought this for my husband, and he practically lives in it. Very good fit, washes fantastically, and is basically perfect for the cooler weather. It’s very comfortable to wear and soft near the skin. Quality item.
Review: Nice and warm & good fit - The size is not tight. It might size down after first wash. We will see. It’s very comfy and keeps you warm. But remember right layers. The socks that came free are perfect. Really good quality Will buy again. I got the 250. Not too thin or too thick.
