We purchased the Coyuchi Winter Weight Down Duvet Insert so our writer could put it to the test. Keep reading for our full product review.

I’m not embarrassed to admit; a cozy full-night sleep has been high on my priority list for as long I’ve been buying my own bedding. For some, a mattress makes the biggest difference in the quality of their sleep, but I’d much rather spend my money on a highly rated, snuggle-worthy duvet like the Winter Weight Down Duvet Insert from Coyuchi. You know that feeling when your bed is almost too good to leave each morning? That’s what I look for. Here’s what I found when I tested and snoozed under Coyuchi’s heaviest luxury duvet insert over the course of the first cold month of the year.

If you’ve never heard of Coyuchi, they’re a coastal-inspired luxury brand specializing in carefully crafted linens made with 100% organically grown cotton. Among many of their bedding bestsellers, their Winter Weight Duvet Insert has high reviews and a loyal fan base. I couldn’t wait to get it in bed to test it out.

The insert shipped in a few days to my front door and arrived in a lovely reusable, organic cloth bag. The bag is great for storage in warmer weather and preferred to unnecessary plastic waste.

My first impression of the duvet insert; it’s light! Before I even put it on my bed, I noticed the almost airy weight of the blanket and at the same time, how generously each of the carefully stitched boxes was filled with 600-fill power pure duck down.

It is heavy enough to keep you warm but light enough to be breathable and keep you comfortable.

My husband commented on the comforter’s soft organic cotton shell and asked, "Does it even need a duvet cover?" I explained that to protect any duvet insert properly, we need to keep it away from direct contact with body oils. This insert comes with loops on all four corners to attach it to a duvet cover of your choice.

Our first few nights under this duvet insert were nothing short of magical. It’s made slightly oversized, which means it looks comfy and drapes dreamily over our king bed's sides. The large size also means there’s enough blanket for both of us to get twisted and comfy in. Finally, no more blanket wars!

We also love how warm it keeps us on cool nights without ever making us feel sweaty or weighed down. It has 55 ounces of fill, certainly heavier (which actually helped me sleep) than an all-seasons insert but lightweight compared to other winter duvet inserts. The insert uses high quality, pure down so that it’s warm and lofty without feeling weighty; it sort of floats on top of you. It is heavy enough to keep you warm but light enough to be breathable and keep you comfortable.

We also began to notice and appreciate more subtle details in the duvet’s construction. I particularly love the stitch-through box construction that keeps the fill evenly distributed, and the down-proof cover prevents any feathers from escaping. 

Frequently Asked Questions

How do you clean this duvet insert?

The Coyuchi care instruction says that you should only need to wash your duvet insert once every two or three years with regular use. When you do (or spill something), it is machine washable using an oversized machine using warm water and mild detergent. To keep the insert’s lofty look and feel, fluff frequently. You can even freshen it up outside in the sunlight every so often.

Can I use this insert year-round?

You can use it year-round, but only if you tend to run cooler at night or if you blast your air conditioner at night. Hot sleepers in the middle of summer will overheat with this duvet—instead, try an all-season option. The higher the down fill number (in this case, 600), the better the quality and warmth. So, while this insert is top of the line and very breathable, durable, and fluffy, it’s best for keeping cozy and warm on cold winter nights. Coyuchi has a generous return policy where you can return any item for store credit within 1 year of purchase, even if it's been washed or used.

Is this duvet insert worth the money?

There are plenty of cheaper duvet inserts that may offer some of the same benefits, but none will have everything Coyuchi does. I love the brand's mission and sustainability standards and believe there is value in products that are low-impact, certified organic, and made in the U.S. because they're better for the environment. For example, the down comes from humanely-raised birds on an Indiana duck farm where it is double-washed and carefully processed.

Features-wise, you can see and feel the high quality of this comforter. If you’re in the market for luxury, this is the very top of the line. The biggest downfall of the high price of this comforter is that it isn't an all-seasons duvet.

Coyuchi Winter Weight Down Duvet Insert vs. L.L. Bean Permabaffle Box Goose Down Comforter (Warmer)

The L.L. Bean Permabaffle Box Goose Down Comforter (Warmer) is the warmest down comforter from L.L. Bean made for cold weather with a great insulator of goose down filling the comforter. The king-size comforter weighs around 9 pounds, 8 ounces. The filling weighs 68 ounces. It is one of the heaviest comforters on the market, costing around $579, which would save you a couple of hundred dollars. It's also well-crafted and comes with a one-year return policy.

Final Verdict

Winter Warriors—buy it!

I wish I lived in a climate where I could use this duvet year-round. With its careful construction, generously stuffed superior duck down fill, and organic cotton shell, it’s the kind of near-perfect comforter I imagine celebrities use. If you live somewhere with long winters and are looking for something to splurge on to stay warm, the Coyuchi Winter Weight Down Duvet Insert is the way to go.
