User Review: The North Face Windstorm 3D
Fill: Polarguard 3D
Temperature Rating: 35F/2C
I will stay away from the North Face Windstorm 3D. The company's temperature rating of 35F for this sleeping bag is overrated. I took it to the sierra in the spring when the temperature dropped to around 35 degree at night, I felt so cold at night I couldn't sleep! This sleeping is way too expensive for its quality. The cheaper sleeping bag in other brandnames could guard low temperature better than this one. Not a good sleeping bag for its price. I don't think it's suitable for 35 degree either. Upper 40 degree maybe!
