When I trekked to Everest Base Camp, I was warned that temperatures plummet at night and the teahouses where we'd be sleeping aren't heated, so I armed myself with an awesome sleeping bag that wasn't just warm but let me sleep in different positions since I'd be spending 11 nights in it.
I took the Big Agnes Torchlight EXP 0 Sleeping Bag, which you can grab for just $337.46 right now in Backcountry's summer sale if you're in the market for a really good bag.
