1st think I do is look inside the seat and see the seams. WOW a shock in quality. I buy these other pants from some other place cheap but they make pants for hot humid environments. They do not hold up great, but it is so dam hot here I have to. Sorry I wonder here, the Treezyn looks great, feels good, not to heavy, great to have zippers on four of the pockets, I travel often, these are perfect. Got the Large, came as the XL used their chart, just a little snug.
