I've always preferred Wranglers for the times I wear jeans but they stopped making the version I bought in the past. At Costco today, I saw these 505's - 95% cotton, 3% polyester, 2% elastane. 14 oz weight in this lighter blue. They are selling for $37 the pair and I must say, for my frame, they fit very well and are remarkably comfortable. Bought two pairs. A couple may remember that I've said I tend to dress a bit more outdoorsy at this time of year (meaning khaki/olive drab twill shirts, small houndstooth or solid flannel/chamois shirts, jeans or tech pants, moccasins around the house, etc. Forgive the poor photo (it's an older iPhone and I zoomed a little before the photo rather than in post so it's a bit pixelated) but I only took it to send to my son and figured how excited everyone here would be as well...
BTW, the web belt looks white on my computer but it's a proper khaki color!
