I'm going to Idaho Sept 15th-21st to do an elk hunt with a guide. I have everything ready to go except the clothing part. I'm completely torn on what to get or need. I have a pile of under armour base layers and planty of good liner socks and wool socks. I have been looking at the sitka line for outer layers, but not sure on what I should get or need. I have looked at the first lite, but the problem with that stuff is you can't see or touch it before you buy it. The weather is going to be all over the place im sure. Also should mention this is a pack in horseback deal as well. Any advice will be much appreciated!
