Features

It’s built with 650 fill power Nikwax hydrophobic RDS down and 20d polyester. These are both good-not-great, but get the job done effectively. Polyester is an uncommon choice for a quilt fabric, but we acknowledge that it’s got a comfy hand-feel, even if it’s a bit heavy and less durable than nylon

The full quilt lands at 26 oz, which is lightweight not ultralight. But again, that’s all to be expected because the price is medium not high.

From a warmth-to-weight perspective, the Corus is on par with far more expensive sleeping bags, and but fairly average for performance backpacking quilts.

No major flaws with this one, but there are some areas for improvement. First even though the “box baffle construction uses mesh walls to maximize own loft and minimize cold spots,” we still think vertical baffles on the torso are a better solution for preventing cold spots.

We also note that the backside of the footbox is fairly shallow and won’t insulate feet quite as well on a very cold night. They seem to imply you could place the end of the sleeping pad inside the footbox, but we’re not sure why you would ever want to do that. In fact, don’t do that!

As with most backpacking quilts, there are very features, which is a good thing! We never bother to attach our sleeping pad and quilt, but if we wanted to, we like the look of the “Removable SynergyLinkâ„¢ connectors. Though what’s best of all is that they’re removable!

As budget quilts go, this one is slightly inferior to the Hammock Gear Economy burrow in terms of price and performance, but the best value/performance blend you’ll find from mainstream retailers.
