Temps - down to 0C
Moisture - varying, but I don't want to have to worry about it
Exertion - high (but this is tricky since I wouldn't likely hike with it on unless needed)

I want it to be my warm up layer for sheep hunting. Last year I drug a Patagonia DAS parka up the mountain. Mistake. It weighs 23 oz with 120g of Primaloft and I can wear it down to -40 in YK. After my hunt I realized a snow dump isn't likely in my sheep spot and can get away with a smaller, lighter piece. It did make a great pillow though.

I always take a hard shell with hood and beanie along so I can get away without a hood on this piece.

Great thoughts everyone! Thanks.
