Eureka! Copper River 30-Degree Mummy Sleeping Bag Description

Rated to 30 degrees Fahrenheit, the regular-sized Eureka Copper River mummy-style sleeping bag features a bag-within-a-bag design, which keeps cold air from the outside from getting through and warm air on the inside of the bag from escaping. The inner layer of the bag is cut smaller than the outer layer to create a consistent thickness of insulation throughout the bag, which prevent thermal leaks from forming.

The trapezoidal foot section is angled to allow for the foot’s natural sleeping position. It has a fully adjustable contoured hood. Other features include a two-way, self-repairing zipper, inside stash pocket, fleece pillow pocket, zipper thermometer and compression stuff sack. This Eureka! Copper River 30-Degree Mummy Sleeping Bag is filled with Eureka’s proprietary 7-hole slickened, polyester Thermashield fiber fill, which provides maximum insulation at the best value possible.

Each Thermashield fiber strand contains 7 tunnel-like holes that run the length of the strand. Each of these holes traps air inside it’s passageway creating dead air space that efficiently retains heat to keep you warm.

Eureka! Copper River 30-Degree Mummy Sleeping Bag Reviews

Got this Eureka! Copper River 30-Degree Mummy Sleeping Bag for my first backpacking trip. Temperatures got down to 35 degrees and I was still warm even without socks or tightening the hood. I bought the long version and it had plenty of room for me (6′2″, 190). However, looking at my friends bags, it was clear that mine was the bulkiest. All in all, a great bag if space/weight is not at a premium!
