Description
DETAILS
The down duvet is inspired by performance outerwear to provide year-round comfort and warmth.
ABOUT CASPER
Casper was created to re-imagine sleep from the ground up, beginning with its obsessively engineered, outrageously comfortable mattress. All of Casper's sleep products are developed in-house by the company's award-winning R&D team, including its airy sheets, pillow-in-a-pillow, and inventive Lounger and Layer designed exclusively for Target.
Casper was recently named one of Fast Company's Most Innovative Companies in the World and its eponymous mattress was crowned one of TIME Magazine's Best Inventions.
FREQUENTLY ASKED QUESTIONS
What's the fill power?
Fill power refers to how much space a single ounce of down will occupy at its maximum loft; or in other words, is a measure of its insulating power. The Casper down duvet has a fill power of 600.
Can I use the duvet with my Casper sheets or duvet cover?
Absolutely, the products work seamlessly together. We designed the loops on the duvet to be used with the corner snaps of the duvet cover. You can also use the Casper duvet with any compatible duvet covers; but we recommend taking advantage of ones with corner loops!
What does all-season mean?
The Casper down duvet is designed for year-round comfort, so there's no need to swap in and out with the seasons.
Sleep on it, lounge on it, dream on it; if you don't love it within 120 nights, you'll get a full refund.

9/10
[This review was collected as part of a promotion.] Very comfortable and soft. Although I think the material could be a little softer, maybe that will come over time and with washing.

Best duvet we could find
[This review was collected as part of a promotion.] We checked all the duvets in store and settled on the down duvet. It is absolutely perfect even for summer use. Can’t wait to use it this winter.

Excelleent
[This review was collected as part of a promotion.] The Casper down duvet is perfect-light weight, fluffy, and with anchor points at the corners to match perfectly with Casper duvet covers so it won’t slip around inside the duvet cover like other down duvets will do! This is the third down duvet we purchased from Casper!

Waste of Money
Purchased this product in 2020 through casper, and without fail, every time I change the duvet cover a ton of feathers come out. The duvet has deflated so much we need to purchase a new one. Save your money and purchase a better qualify duvet - this isn't the one to buy.

Poorly made
Really poor quality. Within a year, tons of feathers started shedding from out of the duvet cover. They not only come out of the duvet, but also out of the Duvet Cover we bought from Casper. The room is constantly covered in down feathers, creating lots of dust and kicking up our allergies. The blanket also bunches up significantly more than other down comforters we've owned constantly requires shaking to loosen the bunched-up features (causing yet more feathers to shed).

Cloud sleep
[This review was collected as part of a promotion.] I was on the fence about buying this, but was so glad I did! As a sleeper who runs warm, this was the perfect duvet for temperature control. It is so comfortable, lightweight, and overall a perfect choice. The duvet doesn’t make any noise in my opinion, and is a great addition to the master bedroom. I look forward to getting into bed each night. Would absolutely purchase again.

I highly recommend it
[This review was collected as part of a promotion.] I am really pleased with my purchase. I was nervous at first as I wasn’t familiar with the brand but the lady and gentleman in the store in West Palm Beach were really accommodating and helped me choose the one best for all my needs. I love it. It’s just the right weight and it feels heavenly

The reason why I got the duvet is because I don't like synthetics in my beddings and this makes the difference!
[This review was collected as part of a promotion.] I love the organic cotton and down duvet that I recently bought, Its cozy, warm, light but with the perfect amount of weight for a perfect sleep. I bought my pillows in casper to so my 8 hours of sleep are ensured! Definitely recommend it to everyone.

Luxury
[This review was collected as part of a promotion.] My husband and I love the duvet, it is so soft and comfortable. I usually get hot and toss all the covers off, this is the only comforter I have ever had that keeps me at the perfect temperature. It feels luxurious.

Gives a Cozy Vacation Feel
I love this duvet!!! I did a bunch of research before purchasing and decided to go with Casper because of other reviews and the dimensions of the product (some comparable brands seemed smaller). It is so breathable and comfy, it keeps the warmth in but doesn't trap heat like my previous comforter. I was a little worried about the crinkly noise mentioned by other reviews but happy to report there is no issue there. I paired it with a nice cotton percale duvet cover and the overall feel of this duvet is giving me those lovely hotel bed vibes I was looking for. Very much recommend this duvet it is so comfortable!

Love it
I am so happy with this duvet and cover. It’s exactly what I wanted, it keeps me warm, but not too warm and it’s so fluffy, not heavy. It’s made really nice and I love how the duvet attaches to the cover to keep it from slipping! Would definitely recommend!

Duvet is supposed to be 650 fill but feels like 50 fill!
I am really upset. This duvet feels like half the size of my last one I bought a few years ago. Its not fluffy, and it makes noise whenever you move. Its like sleeping with paper! So bummed. going to return.
