Familiarity: I've used it once or twice and have initial impressions
After comparing all kinds of sleeping bags for 2 weeks on Amazon, I came across this one (and this site). I decided to buy this sleeping bag because of it's weight and the shape (roomier feet part), and turned out, it's so light, very sturdy, and super warm! We were camping out when it was only 30 degree, all my other friends were freezing because of their cheaper sleeping bags, but i was so warm that when i woke up, my legs were sweaty. Maybe it's also because I put in an extra fleece blanket inside the sleeping bag and had my scarf wrapped around my head while sleeping, but i really thought the money spent on this sleeping bag was worth it. I'm gonna keep it!
