I am looking for a little insight in all around weather on a thru hike I guess. I have been debating between these two bags, 15 and 30 degrees, which is a better pick for a thru hike? would I sweat to death in the summer months with the Helium and Freeze with the Hydrogen during the spring and fall? I am planning to take a silk design sleep sheet as well if that makes a difference. Any insight would be great.
