For me, one of the best things about TETON Sports Mammoth is that it is very easy to stuff it back into its carrying sack; I didn’t have any trouble with it.

Coleman never disappoints, so I was eager to try their Tandem 3-in-1 sleeping bag. The first thing I noticed about it is that it is very spacious! I had more than enough room in it. It is also great for taller campers.

The Axiatic Kodiak also made me feel as if I was sleeping in my own bed; it is simply THAT comfortable! Double brushed cotton flannel is really soft and breathable, and it gives a bedsheet feel. And there is also a pocket inside that I used for storing my phone, to keep it near me all the time.

This is another Coleman sleeping bag I laid my hands on, and I was absolutely delighted! 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.

I really liked how lightweight this bag was. I didn’t have any trouble carrying it (which I sometimes have in the case of heavier sleeping bags). What I like about Coleman sleeping bags is that cleaning is easy as I can wash them in a machine, and the Coleman Biscayne is no different!

Rolling and securing this bag is easy thanks to the roll control design and Quick Cord system, and the bag is very soft and breathable. It was a real pleasure to sleep in it!

The Ozzie & Harriet sleeping bag has a very soft filling, and it felt like sleeping on a cloud! I was very delighted by its comfort and softness!

Although my hubby and I have enough space in this sleeping bag to move freely, the option of separating it into two single bags is a nice touch. There are zippers on both sides, and we could open them and enter/exit the bag without disturbing each other.
