Rated down to 15 degrees Fahrenheit, the Casper Mummy Sleeping Bag from Eureka is designed to offer lightweight warmth and compact-ability at a great price. The Casper features a bag-within-a-bag design that prevents heat loss, blocks out the cold, and ensures an even distribution of insulation. The bag is filled with Eureka's proprietary Rteq fiber fill, which is designed specifically to increase warmth while maintaining lightweight compact-ability. Additional details on the bag include a trapezoidal foot box for a natural sleep position, a fully adjustable contoured hood, and an exterior pillow pocket. The bag has a right side, two-way, self-repairing zipper with a full length draft tube to further prevent heat loss, and is equipped with an interior stash pocket to keep important items handy. The bag comes complete with a compression stuff sack and carries Eureka's product lifetime warranty.

The Casper's mummy shape traps maximum warmth, while the trapezoid-contoured foot box provides space for your feet.

Key Features:

• Rteq Insulation: This is proprietary blend is made up of four unique polyester fibers, each chosen for specific characteristics of denier, loft, weight, and thermal efficiency. This blend is designed to provide a balance of warmth, durability, and compressibility.
• Double Layer Construction: The Casper's bag-within-a-bag double layer construction prevents outside air from getting in the bag, while preventing warm air inside 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 prevents thermal leaks from forming.
• Peached Polyester Lining: This lining is warm-to-touch with a slightly fuzzy texture for added warmth and comfort. The lining is designed to combine the performance value of a synthetic fabric with the soft feel of cotton.
• Trapezoidal Foot Box: The anatomically designed trapezoidal foot box is angled to allow your feet to rest in their natural position.
• Fully Adjustable Contoured Hood and Exterior Pillow Pocket: The hood allows you to cinch the bag around your face for warmth or open it up for ventilation. The pillow pocket holds a camping pillow or soft clothing in a pillow position for greater comfort.
• Two-way, Self-repairing Zipper with Draft Tube: The two-way zipper allows you to adjust ventilation from the top to the bottom of the bag. The self-repairing zipper construction ensures long-lasting quality. The insulation-filled draft tube runs the entire length of the zipper to prevent warmth from escaping the bag through the zipper.
• Internal Pocket: The ergonomically positioned internal pocket holds a watch, phone, or glasses. A hook and loop closure keeps items securely in place.

4.0 out of 5 stars Eureka bag is compact and a great bargain, November 7, 2008

I had four requirements when searching for a sleeping bag for a recent camping trip. The bag needed to be compact, light, moderately priced, and warm. The first three this bag passed with flying colors but the fourth it came up a little short. Based on the price and reviews I choose this Eureka bag and overall I was impressed. The bag is light and the stuff sack works great plus it fits nicely into the lower pocket of my hiking backpack. The bag itself feels nice and it has a few touches like a Velcro strap to hold the zipper handle and an internal pocket that makes it feel like a more expensive product. As far as warmth goes it did pretty well. On my trip the first night it got down into the mid 30's and the bag kept me warm. The second night it got down to about freezing and I woke up early in the morning a little chilly. I grabbed a couple of hand warmers, tossed them in the bag and I was warm again. The 15 degree rating may be overly optimistic but I would say that if you are going to be in above freezing temps then this bag will be fine. However if you will be getting into much colder temps you may want to invest in a higher end goose down bag.

I could see this bag being tight around the shoulders if you are a bigger guy/girl. I'm 6'2 and about 170 lbs and the bag fit me fine. I actually went with the long but it is a little too long... I would have been better off with the regular. Also, I would recommend paring any sleeping bag with a light weight pad (preferably self-inflating) to help with comfort and warmth.

5.0 out of 5 stars sleeping bag review, November 2, 2007

The Eureka Casper sleeping bag is excellent. It is warm, light weight and compact. It is a great bag for camping or backpacking. The included compression sack allows it to fit into an internal frame backpack. It is large enough for an adult to fit into but small and light enough for a youth to easily carry. It satisfies the temperature rating and makes staying warm enough possible. To receive these qualities at the affordable price was amazing.

I would not have purchased this bag from amazon except i had a gift certificate. When i got the bag, the manufacture date was well over a year ago which means it had been stuffed in it's stuff sack for at least a year which is by any account not good for the temperature rating of this bag. Other than that, it's a great bag for the price/weight/size.
