Sitka timberline
Just finished two weeks of hard hunting for elk with my First lite Kanabs that I bought right before the hunt. I was really impressed, they wicked, kept me warm but we're breathable. I was worried about merino outer layer but we were in thick country and no rips. Was really impressed with them might buy another pair in camo. I bought and wore these in lieu of my sitka ascent pants.
Kuiu attacks get my vote. Breath nicely, super tough, dry quickly, comfortable and don't cost a huge amount of money.
You guys that wear Carhartts for mountain hunting are a special breed - to each their own I suppose, but nothing could be worse, IMO, than hiking up in wet, heavy denim. Nevermind the fact that they would never dry out......
