Any input on the warmth comparison of a vest with around 5 ounces of 800 fill down, vs a jacket with around 3 oz 800 fill down? I am specifically looking at the Feathered Friends Daybreak hooded jacket vs Hyperion vest. How have you found these, or anything similar that you used in the past?
I'm looking for a 3 season, lightweight piece that can be layered under a wind shirt for added warmth. I would need this down into the low 30's, or even 20's on occasion. Colder than that I will have my winter jacket on the trip.
Thanks
