Eureka! Casper 15-Degree Mummy Sleeping Bag
This appears to be a high-quality sleeping bag which is very comfortable and warm.
Rating: 5 / 5
The sleeping bag comes with a great compression bag. The bag is compact and lightweight. I used this bag on our first winter snap in Florida. The temperatures foretasted the camping weekend in the lower 30′s. The sleeping bag fitting was snug for my 5’9″ frame. When temperatures dipped into the night, I felt the cold penetrating my clothes. I think I’ll need to wear thermals for our next winter trips. (We rarely own winter clothes in living in South Florida) Overall, great bag.

I picked this bag up and took it on a backpacking trip which turned cold. The first night I went to bed and my thermometer said 27 degrees at 10 pm. I was very toasty in the bag. The second night it was 18 degrees and I awoke to sleet hitting my tarp at 5 am. I was also quite warm and comfortable. The last night was 13 degrees at 10 pm (I’m not sure how low it went beyond that). I was warm and comfortable in the bag until about 5 am. This night I used the bag in a tent instead of under a tarp and the moisture in trapped inside from two people and a big dog dripped back on the end of my bag. I woke up and was warm, but my feet were cold. I turned on a light and looked at the bag to discover ice had formed on the bag where my feet had rubbed against the walls of the tent. I put my sweater over the icy spot and went back to sleep. My feet were warm the next morning. All three nights I slept in a t-shirt and boxers. Normally, in cold weather I sleep in my clothes which add an extra layer of insulation, but after reading the other reviews I decided to throw caution to the wind and test the bag out.
I noticed that the bag will not keep you warm unless you cinch the mummy drawstring tight and seal the air out of the bag. I can only guess that other reviewers either didn’t cinch the string or fell asleep against the outside wall of a tent. Also, this bag is a bit big for my tastes as I like to hike with a tiny alpine pack. I used my bigger bag (it’s about what a ‘normal’ backpacker would use) on this trip and it fit easily inside the pack. Overall, I think it’s a great bag. I wish it didn’t weight 3 pounds, but for the price I doubt one could find a cheaper bag that has this temp rating.

I ordered two of these sleeping bags for me and my 11 year old son. We enjoy short backpacking trips, so the Eureka offered a warm bag at reasonable weight (without the cost of a down sleeping bag). When our sleeping bags arrived, both my son and I tested the bag on our den floor. Based on our trial, I returned one of the bags, keeping one for my son to use.
Basically, this bag does not provide sufficient room across the check unless you are a below average size. I am about 6 foot-2 inches tall, and about 205 lbs. I could fit in the bag, but could not see myself being comfortable if I chose to fully zip the bag, sleep on my side, etc. With the bag fully zipped, I could fit in the bag by laying flat on my back, with both arms by my sides (still it was a bit snug).
My son used his Eureka one one of our first cool weather hikes (and had previously tried it at a local campground). For this trip, the evening temperature dropped to just above freezing (most likely about 34 degrees). My son wore some thermals and a beanie, and said he was comfortable in this bag. We also toss a couple of Hothands 2 Value Pack 10 Pair in our bag to add a bit of warmth.
Since I found this bag to be too constricting, and since I am a very warm sleeper, I ordered the Slumberjack Super Guide 30F Regular Right Sleeping Bag which I noticed has nearly the same weight as the Eureka.
Overall, I am pleased with the purchase in terms of quality, weight, and warmth. However, the Eureka only gets 3 stars due to the size of the bag.

I purchased the Casper to use on fall camping trips in the NY Adirondack Mtns. I chose it over the North Face Cat’s Meow due to complaints of that bag’s cold weather performance. I was impressed with the look, feel and overall weight of this bag. With a little effort, it compresses nicely into it’s tiny stuff sack taking up far less space in my backpack than my previous bag. When you take it out, it quickly becomes lofty again!
During my recent trip, the overnight temps fell to the mid 30′s and I remained comfortable. I sleep in a 2 man dome tent and use a canvas “Allagash” cot. When I added a thermal sleeping pad, I felt almost as if I were sleeping in my bed at home!
This bag is very comfortable with lots of toe space but tends to be tight in the chest area. I am 5’10″ 220 lbs and feel near the limit of it’s capacity. If you are a larger person or just prefer more room, you should consider a different bag.
At 1/3 the cost of most comparable bags, the Casper is a great value and has the weight, size and features of the more expensive bags. If the fit is right, I highly recommend it.
