Corus HD Quilt

Updated just in time for 2019, the Corus HD 32 Degree Down Quilt is a little wider, a little longer, and a little lighter, yet still delivers superb warmth and luxurious comfort for minimalist backcountry travelers. Now weighing in at only 1.3 pounds at a regular length, and packing down to a compact 10 x 7 inches, this bag is easily stored in your pack when you're trekking for long distances to remote backcountry locales.

Lofty down insulation traps precious warmth from escaping on cooler evenings dipping into the upper 30s. This down insulation features a Nikwax hydrophobic treatment that sheds overnight condensation and dewy mornings from compromising its loft, so you'll remain toasty-warm even if it's a bit wet outside. And to retain even greater heat, ThermaCapture seams employ a heat-radiating coating that keeps body warmth locked inside the bag, as to prevent heat loss to the cold air surrounding you.

Seeing as Therm-a-Rest is renowned for their sleeping pads, it only makes sense the Corus HD Quilt features Build a System perimeter snap loops that mate with another Therm-a-Rest pad, quilt, sleeping bag, blanket, or sheet. This 2019 model also features an updated footbox, newly shaped to slip over your pad and eliminate chilly drafts.

Great change from a bag

I've put it through the wringer
True to size

Since I purchased this I have thrown my sleeping bag in the closet and never giving it a second glance! It’s so much lighter and more convenient than any bag I’ve tried to date. I run fairly warm so don’t need a great deal of insulation when I sleep, especially if I am sleeping in my base layers. This complements me perfectly along with my Klymit Static V2 and I have used it in temperatures in the low 30s with no base layers on and was comfortable. This has been my go to sleep system for the last 3 years and over 100 nights in the mountains. If you are the type of person that needs to stay extremely warm when you sleep or runs cold this may not be the system for you, but it is absolutely perfect for me and I would highly recommend it to anyone looking to get rid of their bulky sleeping bag to make more room in their pack. It is also worth mentioning that given the nature of the Hydrophobic Down it is important that you use the separate storage sacks and travel sacks to avoid long-term compression. Finally when you unpack it take a moment to fluff the down to restore the R-value, relatively easy but if neglected can drastically wear down the lifespan of the top quilt or result in an uneven heat distribution. All in all a five-star product when used properly with a good inflatable pad and pillow.

Quite possibly my worst purchase

I've used it several times

I REALLY wanted to, at a minimum, like this quilt; however, this is truly the worst choice I have made for my backpacking gear...and I bought a $65 lynx tent for my son, who sometimes goes out with me, which we like better than I like this quilt. I fully understood that a 10 degree lower than advertised temp tolerance should be accounted for with a quilt when opting for this route. I used this quilt with a Therm-a-Rest NeoAir XTherm pad. I sleep super hot and am enjoying the experience of menopause and night sweats, but despite all that, I am so frozen in ~45f temps with this quilt that I cannot sleep. I have had two entirely miserable trips with this thing which included sleeping in my wool base layers, down Patagonia puffy, two pairs of thick wool socks I keep just in case... An. Emergency. Blanket., and crying for half the night due to exhaustion and cold. It actually makes 45 degrees feel worse than freezing somehow. Daylight is completely visible through the very thin quilt. Otherwise...for positive attributes: the seams feel well taped and not a source of drafts, it is a nice length for a person who is 5’4”, and the side baffles do help hold the sides down to keep drafts from coming up. I am not sure I would recommend it for summer camping, though I have no experience during hot nights I can say that the fabric feels like it would be sticky in any kind of humid or warm environment. I do not recommend it for spring camping and certainly wouldn’t dream of taking it for even an extra layer in the winter-a sheet would be more effective.


Does this quilt include the snap attachments that stick onto a sleeping pad?

Hey Daniel! Yes it does. It has the Build a System: Perimeter snap loops and included loop kit mate with a Therm-a-Rest mattress, another quilt, sleeping bag, blanket or sheet.
