I've worked and lived on the water all my life. Been wearing these in 100% cotten for 30 years. Tried all different brands, these are the best. Neck doesn't bag out, nice weight material. They wear like iron. Once the cold weather sets in, I wear them nearly every day. Good under a shirt or on their own.
I bought this for my husband who rarely dresses up. He wore it under a sweater and got many compliments. They fit nice and wash up well. I bought 2 more in different colors.
