I've been wearing (and wearing out) the good old loose fit double knee (Khaki) work pants for years now. In fact that's all I wear. They look good and hold up well and when worn out I use them as work pants (outside or in garage.) Funny thing is years ago I was a bit thinner and was size 29W (and I had to have a seamstress--my mother--take in the waist which was quite a job to separate the waist band internally in 3 places to make even,) and I would order size 30 waist with an un-hemmed leg length. My mother would custom size these up for me and I loved them since they fit so perfect. However, now that I am getting a little older (and bigger around the waist)
I can order a 32w-34L and just have the length shortened by an inch or so. Again, a perfect fit! I personally like the wide leg at lower part of pant leg (I never got into the skinny jeans style.) The only thing I hope is that you don't stop making them.
The pocket on side side of the leg is of great use.
