Thanks for the info about the HH refund. I will call them right now.
I like the idea of sleeping in a hammock but it was just too cold. At high altitude it really gets cold at night. It was about 40° last night and during the day 75°. I realize I can be warm with enough pads but then it is not really ultralight. I also found that I toss and turn a lot during the night and I was always touching the cold hammock sides.
