David, Try looking for schoeller pants from Patagonia, BD, and Arc'Teryx. I have a pair from Patagonia called the stretch guide pant. I like them but my only complaint is they have weak elastic in the waist. My brother owns the Arc'Teryx pants and he has the same problem I do with the waist/belt. I put suspenders on mine an it help, but I think that could be avoided with better desighn. Hope that helps
