  • great sleeping bag for warmer temperatures
Style: Regular
This bag is well made and packs easily into a small sack. I often use it for sleeping at my workplace and the cube storage bag is perfect for my office locker! So far I have only used it a 70F and I am very comfortable sleeping with the zipper down. I like the look and feel of it. I generally only use sleeping bags down to about 20F above their rating and this feel like I would be comfortable down to about 50F zipped up. ... show more

  • Cheap Zipper / Doesn't Breath
Style: Regular
This only gets a second star because it actually is really light. The rest is not worth the money. The zipper separates to easily and you have to fumble to fix it at night in the tent. The material is very strange. It doesn't really have any breathability. Even if your not too hot your body moisture seems to stay in the bag, so it feels like you are sleeping in a gargage bag. ... show more
