Hey everyone seeking advice on a sleeping bag. I've got about a 250$ limit and was looking at the mountain hardwear hyper lamina or the kelty sb both in 20 degree. The hyper lamina is synthetic and the kelty is 800 down fill, i can get both for about the same price. just wondering if you guys had any experience with these. I'll be in northern utah using the bag for backpacking and hunting from early spring-late fall.
