The Nemo Rave 15 is a comfortable, feature-filled product. We like its soft liner materials and lofty down filling. It kept us warm on cool nights, and the “spoon” shaped design is roomy for side and stomach sleepers who feel constricted in a traditional “mummy” bag. We are disappointed with how much this bag weighs for a down-filled bag, and think it is on the expensive side for what it is.
We would take the Rave on short backpacking trips in cool climates, but would not recommend it for longer self-supported trips due to its weight. It's a comfortable option for car campers, especially for side sleepers.
Our Analysis and Test Results
Although we can't exactly give it rave reviews in all metrics, the Rave is very comfortable, warm, and chock full of features. We gave it high marks in the comfort, warmth and features department because it is jam-packed in all those metrics; however, it lost points for weight and packed size.

Warmth
The Rave is a cozy, lofty down bag. It has 18 ounces of 650 down fill. It is EN rated to 15.4 F. We don't think that it would be comfortable down to this temperature but would probably keep us warm down to 25 degrees or so.

The problem with Rave's “spoon” shape design is that it's super roomy, which is great for comfort but allows for “dead air” to hang around. The dead air cools and keeps the body cooler. The Rave has a “blanket fold” instead of a traditional baffle to minimize warm air from escaping through the neck hole and can be pulled out for better venting. However, we find that the blanket fold is more like a “smother flap” and often we woke up with it flapping in our faces - instead of remaining tucked in or folded back.
Weight
The Rave weighs in at 48 ounces, which is quite heavy for a down filled bag. Usually one of the main advantages of a down bag is they are lighter weight, which is not the case for the Rave, which is one of the heaviest bags in this review.
Comfort
It seems like NEMO's main focus is in the comfort department. The Rave is a comfortable bag, with the “spoon” shape for ease of movement, soft liner materials and other features meant to enhance the comfort of this bag…and it works.

Packed Size
The stuff sack that the Rave comes with is not exceptionally small. However, if you have a smaller stuff sack or compression sack, the Rave will get smaller than its current stuff sack. Because of the extra features like the “Thermo Gills,” this bag will not pack down as small as some others.
You can vent the Rave by opening these “gills”. We're not sure how effective they are, but they look interesting.

Features
The Rave has lots of features and you can be the judge of if they're valuable or not. We tend towards the no-frills high-quality material, lightweight bags that earn top marks in this review, but if you're looking for extra bells and whistles, the Rave has them all.
We've already mentioned the interesting “blanket fold” that replaces a neck baffle. If you want more venting without getting a draft, NEMO has introduced “Thermo Gills,” strange zippered vents you can open without exposing the inside of the bag to drafts from outside. Our favorite feature is the pillow sleeve. It's convenient to stuff some clothes in there and have an instant pillow.

Value
We don't think that the Rave is a great value for its price. It's expensive and doesn't offer the same performance features as other less expensive options.

Conclusion
The Nemo Rave 15 is a comfortable bag that comes with lots of bells and whistles. If you're looking for a warm product that has lots of room for your legs, this may be it. However, we think you'll find better value elsewhere, as there are lighter and cheaper options in this review.
