Converting back to Sitka after wearing First Lite for the last few years. I'm a little torn on an outer layer for a September Elk hunt in Colorado. I'm a fan of Merino wool for next to skin so I'm keeping a couple First Lite short sleeves but primarily I'll be in Sitka's lightweight merino long sleeve quarter zip, an ambient hoody and then either a Traverse Jacket or a Mountain Jacket. I have the Traverse jacket now but I'm thinking of returning it in favor of the wind protection afforded by the Mountain Jacket. Anyone have any thoughts on this?
