I have the Kanabs and love them, but they aren't cold wx gear. I couldn't find a pair of gila pants that fit (I'm a 38x34). The Kanabs were he redesign of the gila following the sizing issues. Not sure if they are going to discontinue the gila or not.
I have returned for exchange the Kanabs due to some holes and fading issues. The rip stop prevents tears from getting larger, but these aren't brush buster durability. Otherwise, I love these pants. Apparently there is a button down shirt in the same material in the works for June 2012.
