I own several LLbean mocks. This one and the red stripe included. They fit well. They wash well. After 20+ washings they both look as good as they did new. Perfect over a "T" or as the first layer under a classic chamois shirt, flannel, or blazer.
Have several of these mock T-necks in different colors. Great for everyday wear in fall & winter here in Northern VA. Holds their fit; not too much fading over a couple years wear.
This is a very nice mock turtleneck. The weight is not too light or too heavy, but is good for all seasons. My only complaint is that the tail is too short resulting in the "plumber's crack" when you bend over. I am 5' 11" tall and weigh 185 lbs. but the large size, which Is otherwise roomy as I prefer, has a too-short tail. Add a few inches to the tail and this is a winner!
Won't work for men who are tall and slender. Sleeves are not very long and baggy. This top is way too wide and definitely not "preppy chic," just big and dumpy. Too bad, it's going back.
