My cousin and I are big elk hunters. We were looking at doing some backcountry hunts. And trying to go as light as possible. We have looked at the Eagles Nest One Link ProLite. And some of the Hennessy stuff. We will be hunting around the 1st to the middle of September in Colorado, Wyoming, and maybe, hopefully Utah. Does this foot the bill you think. Also do we need an uderquilt you think and how heavy of a sleeping bag? Looking for everybody's opinion. Thank you.
