For warm to cool weather I've had good luck with Sitka Ascent pants, just adjust my base layer underneath depending on temps; fit is relaxed, two large cargo pockets, deep pockets, but no rear pockets. They've been pretty damn sturdy, especially considering the fabric weight, but I did suffer the my first tear this past weekend after two years of pretty hard hunting- about a 3" tear in the thigh near the knee (crawling over/under/around one of the most hellish blowdown messes ever!!)- sending in to have it repaired.
