Product 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 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.

This sleeping bag strikes the balance between cost and quality. I've slept snug as a bug in many different setting in this pack, from just under freezing to about 65F. The fleece pillow pocket is great for a folded up jacket, and the thermometer on the zipper is a nice touch. It's lightweight and compactable, perfect for backpacking. I plan on using it into the spring and summer, where it should be perfect for the cool evenings on the mountainside.

1.0 out of 5 stars Really a 35-degree bag, October 7, 2007

Eureka Cimarron 15 degree bag is a nice cut, design and comfort bag. The issue is in meeting the 15 degree specification. I specifically bought this bag for early spring and mid to late fall camping/treking. Recently in the Adirondack's I hit a few nights of frost, first night was a pretty hard frost which required longjohns, hiking socks and a skull cap to get through the night without shivering my tail off. Spent a couple more weeks treking and temperatures warmed so that I feel the bag may offer comfort to about 35 degrees at best. To rate it a 3 season bag is really stretching it.

This review is from: Eureka! Cimarron 15-Degree Mummy Sleeping Bag (Sports)

Bought this sleeping bag for a backpacking trip along the Alabama Pinhoti trail. It worked beautifully for the sub-50-degree weather. I'm a 5'9"/190lbs man, and I fit comfortably in the regular-sized bag (with 6"-8" of extra length). There's just enough room in the width for me to roll over, but not much more than that -- of course, mummy bags like this aren't intended to be (nor should they be) too roomy.

It's not the lightest bag out there, nor the most compact. You could probably find a North Face, Marmot, or Mountain Hardwear bag that would certainly outperform this sleeping bag. -But, for the price, this bag is very hard to beat. Eureka makes good, quality products (I own a $300 Eureka tent that lives up to it's price), and this bag met up to the quality I've come to expect from Eureka.

If you're expecting actual 15-degree weather, you might look into a warmer bag -- this one will certainly keep you from freezing at those temps, but it likely won't keep you all warm & cozy.

Would I recommend this bag to a backpacker on a budget? Most definitely. :-)
