I wear a size XL, so I bought a size XL, and it's somewhat large, and very long, but so soft and comfortable. I think next time when I order this, I'll order a size smaller than what I take. The only reason I gave it 4 stars is because it's very long. Great for tall men, not so much for average height men.<a data-hook="product-link-linked" class="a-link-normal" href="/UltraClub-Men-s-Egyptian-Interlock-Mock-Turtleneck-T-Shirt-XL-Heather-Grey/dp/B0038MR6HC/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">UltraClub Men's Egyptian Interlock Mock Turtleneck T Shirt, XL, Heather Grey</a>
