Great pattern
Hubby was having trouble finding what he wanted in ready-to-wear, so I tried this pattern. One with stretch cotton jersey. While it is not a heavy fabric, he quite likes them and finds them comfortable. I made a second pair in a nice cotton spandex doubleknit that I found online in Hamilton, ON. They are heavier and will be warmer. Either way, he is very pleased with the result, and I found they were easy to make. Lived up to the Jalie reputation for great patterns!

Great Pattern!
I have used this pattern for a number of years for both my husband and son -- my husband works construction and I make these out of fleece for him to wear under his work pants. He loves them and requests more as the older ones get ratty.
