The Cooper R-7 is our smallest and lightest sleeping bag. It is great for warm weather camping, travel, and as an insulated liner to give a rectangular sleeping bag a temperature boost.
The Fatboy 400 is huge! It has all the extra room you need for 4 season camping. And compared to other sleeping bags of the same size and temperature rating, this Fatboy is still the leader in compact/ lightweight.
The Roma is a great 2-3 season sleeping bag. The short tapered shape is perfect for anyone under 5' 6″ (168cm), providing better thermal efficiency than a full-size sleeping bag, all in a compact size and weight.
The R-400 works as a lightweight and compact 4 season camping sleeping bag. The rectangular shape provides lots of space for a comfortable sleep, and the added insulated hood helps keep all the warmth in.
