Port Authority Interlock Mock Turtleneck (K321) Available in 10 Colors

All the other brands--including LL Bean--brag about the thick, heavy 7.4 oz fabric from which their mock turtles are made. That's fine for outdoors but when you wear those bad boys indoors under a shirt, you will cook. Just bought a pair of Port Authority mock turtles and their 6.3 oz cotton is the perfect weight. Not too hot indoors, not too cold outdoors when worn under a shirt. Oh, and they're well made, comfortable and attractively cut, too.

Good product and good service, I find that these shirts are a now better quality now that Sears has taken over Lands End and the quality has slipped and price went up.
The only problem I find is the freight on these items at $5.95 apprx. price per shirt they overcharge especially if you order multiple shirts they do not give you a break although they are all shipped in one bag..

I wouldn't call myself a fanboy but I bought this for a Halloween costume. I don't think they're preshrunk so my medium looked like a large but after I washed it, it shrank a little closer to my size.
