Since 1989, Down Under Bedding has handcrafted Down Duvets and other bedding to provide a relaxed and comfortable night's sleep. After years of research, Down Under has invented the World famous Jasper Duvet.

The filling is made from large down plumes derived from adult geese, the most premium down available. It ensures superior softness, high loft, and maximum insulation. The down is cleaned and processed according to the Down Association of Canada standards to make it 100% Hypoallergenic. 

World Famous Quality and Comfort

This luxurious, Eco-friendly down comforter is proudly Made in Canada with 100% Hutterite White Goose Down, one the highest quality down clusters in the world.With its 850 fill power, this duvet has the best insulation efficiency.  It gives you all of the warmth you desire without weighing you down. 

The baffled box design holds the down in place, giving the duvet a nice and even thickness throughout. The down-proof outer shell is made from a 500 thread count 100% cotton fabric which is remarkably soft and only improves the breathability of the duvet. Bring an authentic 5-Star Resort experience right to your bedroom.

Equipped with corner ties to attach to the inside of your duvet cover, which prevents it from shifting around inside. It is very important to utilize a duvet cover to protect your duvet and keep it looking new and clean. 

Fill Power Vs. Fill Weight 

Fill power is the measurement of loft or fluff within your duvet.  The quality of a duvet is measured by fill power. Higher fill power means a higher quality duvet. It is tested by measuring the amount of space 1 oz of down takes up within your duvet. The more space it takes up, the higher the fill power.

Each ounce of down has nearly 2 million filaments that interlock and overlap to form a soft cushion, which gives a duvet its loft. Higher fill power means a lighter and fluffier comforter. The fluffier the duvet, the more air pockets it has to trap heat. 

Fill weight, on the other hand,  is the total amount of down used to fill your duvet and is usually expressed in ounces. Fill weight is the main component of warmth for your duvet. The more down put into a duvet, the warmer it becomes.

Best Comforters- Ever!

I bought my original comforter from Down Under 25 years ago. Back then they had a store in Toronto. I saved for months to buy it & it served me well for all these years.
Recently down started coming out of my well worn & loved comforter, so I decided to buy a new one. Found the Down Under website & wanted a couple of questions answered so I also called them. My questions were helpfully & happily answered & I purchased this comforter which delivered in two days.
This comforter is the most comfortable and luxurious bedding I’ve ever slept on. Three weeks in & my wife and I can’t stop talking about it. I’m going to bed earlier than usual just to lie in this cloud of cozy comfort.
On top of how great the comforter is, the customer service is top notch. My questions were answered. They sent me a hand written thank you note for being a customer & added a pair of lovely bamboo pillowcases as a thank-you gift.
I HIGHLY recommend this specific line of comforters & Down Under. Kudos for quality & top-notch customer service!

Thanks, Rodney, for sharing your most valuable feedback

It has no bad smell and no noise from the cotton cover. It is very comfortable. I am happy to try this one. I really like this brand more than others.

Excellent as per many other excellent reviews

I researched what felt like a thousand down comforter reviews and so many had mixed reviews. I looked for hours as to what to buy, who had the best quality, what weight and fill I should get ....everything. I finally decided to buy from Down Under. Their shipping was prompt and with paying in Canadian Dollars the pricing was very fare. The comforter and Duvet cover for the comforter was excellent. The one issue was the color we wanted for the duvet cover was inaccurate as displayed on the website...but we liked the color we received. Buy from these people, you will not be disappointed. Quality is a must with this type of purchase and you will get the highest quality with Down Under.
