It is amazing for use in cold weather, and unlike most sleeping bags, rated for higher temperatures, the Coleman Big Game can be used for camping in temperatures as low as 0°F! It will keep you warm even if the temperature dips below freezing!

Although my height is average, my husband is tall, and he doesn’t feel comfortable in just about any sleeping bag. However, this Coleman model was perfect for him, and he even had more than enough room to move his legs comfortably. This sleeping bag is long enough for people up to 6 feet 7 inches in height!

Another thing I wanted to share with you is the comfort of this bag. Oh, the comfort! Thanks to the ComfortCuff feature, commonly used in Coleman sleeping bags, my face was surrounded with softness, and I slept like a baby! I didn’t want to get up in the morning because I was so comfortable.
