5 stars!!!  These are extremely comfortable and warm.  The XL was a perfect fit, just like the shirts of the same make. I don't wear them a lot, because they are so warm, so just on really frigid days.  I purchased these to go with the shirts that I got beforehand and was extremely happy with.&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Duofold-Men-s-Midweight-Thermal-Crew-Navy-X-Large/dp/B000VW2QB8/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Duofold Men's Midweight Thermal Crew, Navy, X-Large</a>

These didn't go through any shrinkage when washed with cold water, unlike myself.  I do wear them as sleeping pants so much that I am concerned with my personal hygiene.  That is a credit to these pants, not a fault.  I will have to order many more soon!
