This is a great sleeping bag! I was a little skeptical at first due to its low price but this bag has done nothing but provide many a warm and comfortable night! While many of my friends complained of being cold at night, I enjoyed hours of uninterrupted warmth.

The bag packs rather small and fits comfortably at the bottom of my ruck sack. I recommend this sleeping bag to anyone who wishes for a warm and comfortable nights sleep!
