I was planning a hike in Nevada’s Incline Village. I started researching my gear choices.
Base layer is Columbia base layer with omni-heat in both the shirt and leggings.
The green pants are just some hiking pants that I planned to use in Florida but tried in the winter. The mid layer is a Columbia softshell with omni-heat.
The outer layer is a froggtogg that is waterproof but with no insulation.
Lastly Columbia omni-heat glove liners, american flag schemog, baliclava, and ski gloves.
Lastly I had a CamelBak 18L pack with some essential emergency gear and some basic food.
I tried this setup in a number of different configurations. I found my core temperature swinging in all directions. At one point I was completely soaked. Also I found that it was not comfortable to just stand still. This setup was effective when moving.
My first hike was a FAIL in that we did not get very far and so during the second hike I skipped the outer layer and stuck with the base and mid layer. But since I was moving and generating plenty of heat I found myself venting the extra heat through the collar. The only challenge might be that the midlayer is not very waterproof.
And my only complaint about the CamelBak is that the straps are small.
