Poorfag here, I'm gonna go on a 5-day long trip to hike part of the Appalachian trail with some friends (who I will share a tent with). They all have good sleeping bags except me. All I have is these gargantuan excuses for sleeping bags. I've been recently wondering if I could just use a blanket instead. I don't think the summer nights on the trail would drop down further than 40-ish degrees (fahrenheit). If I can use a blanket that would keep me warm, and not take up as much space as my giant sleeping bags, that would be a lot better. I'm just wondering if it's possible to do that.
