Sorry, no thanks.
This material, whatever it is, has almost ZERO FLEX. I bought these for bicycle commuting / wearing for factory work and they're NOT USABLE. The inflexibility causes 2 major problems: (1) inhibits range of motion on my legs (HUGE problem, even on the 3/4 pant); and (2) The legs gradually ride up so you have to keep pulling them back down (on the 3/4 pant); AND the waist rides down so you have to keep pulling it back up. Bought 2 separate pairs of these, and can't use either one - both have the same problems.
