Compressibility
The 650-fill and the generous sizing add up to a bulky package. When full stuffed and compressed, the bag fills a 9- by 17-inch sack, making it the largest of our packed bags.

Warmth to Weight
Though rated to 15ºF, we found the comfortable limit to be the mid- to high-20s, in part because there was some excess space inside which, though great for mobility and comfort, draws off heat. The 650-fill down provides good insulation, but also drives up weight. The result is a relatively modest warmth-to-weight ratio that calls well short of most of the other bags in the class.

Comfort
The broad hood and generous cut in the upper bag meant that even with my somewhat broad 46-inch chest I could easy twist from my back to my side without feeling constrained by the bag. The foot section also proved roomy and comfortable. The taper in the knees was a little more snug, but not constrictively so.

Durability
We found we frequently caught shell material in the zipper especially when zipping the bag up. But that was the only cause of concern in terms of durability.

Value
Though the bag utilizes a less expensive 650-fill down, the price remains near the $300 range, where dwell other bags sporting 800-fill.
