THE WEIGHT GUIDE
One duvet. Three climates. Every type of sleeper.
Not sure which GSM is right for you? Here's exactly how to decide.
150 GSM
Spring / Summer
Light Duvet Insert
An airy, breathable layer for warm nights. Light enough for hot climates and hot sleepers, but still provides the cocooning feeling of a duvet over just a sheet.
Best for: Warm climates · Hot sleepers · Spring/summer use
Shop 150 GSM
350 GSM
All Season Duvet Insert
Perfect All-Year Weight
The weight that works year-round. Warm enough for cool autumn nights, breathable enough for mild summer ones. If you're not sure which to choose — choose this one.
Best for: Most sleepers · Year-round use · Moderate climates
Shop 350 GSM
500 GSM
Winter
Extra Cozy Duvet Insert
Maximum loft and deep warmth for cold nights and cold sleepers. Still breathable — unlike heavy synthetic fills that trap heat without releasing it — just more of everything.
Best for: Cold sleepers · Northern climates · Winter use

Amazing - breathable - sustainable
"Breathable, best quality and temperature control I’ve found!"
Great comforter
"Beautifully made with excellent quality. LOVE the hard-to-find 8 tabs for securing my duvet cover. Highly recommend."
Cooler Nights
"We've used our organic cotton air duvet now for a little over a month. we like it well enough - does seem like it keeps us cooler at night. we've taken it to the dry cleaners and have not noticed any difference in the fill. I like that it's bigger than our last duvet because my husband is a cover hog."
Perfect for my bed
"Love this duvet insert. So light and comfortable and feels really clean. Very happy with it."
Perfect!
"Perfect! I was really worried it would be too warm or not warm enough. I read reviews on this brand and several others. This seemed to be my best option because I can switch them out or use them together. It is still getting into the high 80s here and the all season layer is what we are currently using. It will probably be enough for the winter months, we rarely get below freezing. I may use the light layer during the summer months. I am usually a very hot sleeper and wake up drenched to the point of having to shower but so far I have had no problems with getting too hot. Will probably be purchasing for our grown children as well. This is our first wool duvet, really glad I went with this one!"
Only a week in and we love it!
"We've only been using the wool 3 in 1 duvet insert for a week or so, and I'm already so glad I purchased it. We are using the all season insert as it's fall now, and I love it. We don't sweat like we did prior to using this wool insert. We still get a tad warm sometimes but nowhere near as bad as before we started using this wool duvet insert. The cotton material of the wool duvet insert, the cotton of the duvet cover, along with the cotton of the flat sheet seems hold it all together and the bed doesn't seem to get as crumpled and messy as it did with mixed fabrics (cotton & polyester). I am looking forward to trying the summer insert in my duvet next year. I'm donating my polyester insert. If you're on the fence, make the leap and get one."
3n1 with Microfiber fill
"Love this. Researched many different brands, didn’t want to pay $500 and also didn’t want cheap plastic fill. This was the best option, no chemicals, organic cotton, works perfect inside my new linen duvet. I love warmth level options so I’m comfortable all year round"
It's my second purchase
"I have both organic cotton king size comforters and the Percale sheets. They are great. Wish the king size comforter was a little wider but it still fits well."
3 in 1 wool comforter - SO pleased!
"I got the 3 in 1 wool comforter, so can speak to both the quality of the spring/summer weight and the all season. This is a really high quality product and I love that it is wool fill. Wool is sustainable, natural, non-allergenic for many, and temperature regulating. I don't overheat at all (which is a problem I have had with down and poly fill comforters) but am perfectly warm. The comforters are not as "poofy" as normal down or poly fill comforters but still very substantial, especially with both snapped together, and have a really comforting weight to them that really helps me sleep. Wool does have a "natural" smell especially when fresh but I found it in this product to be very mild and comforting, and it faded quickly with use. It is a sign that the wool is real and high quality anyway. Customer service was spectacular, there was an unexpected issue with my order and the team went above and beyond to make it right. I don't leave a lot of reviews but I am so happy with my Delara comforters!"
