  • Great!
Size: King Color: Grey/Heavyweight
This down comforter is very good and very warm especially in cold temperatures. It’s fluffy and lightweight, but it is very efficient. I am very happy with my purchase.

  • Durable and long lasting, cool and comfortable
This has become my favorite summertime comforter. It's simple but well made, cool and comfy, and washes well. Been using it over a year now and it still comes out of the washing machine looking like new. definitely worth the money.

  • Fantastic!
Size: Full Color: White/Heavyweight
This comforter is very high quality! The cotton cover is good and dense so that no fuzz escapes at all! The comforter also has, double sewn seams and, the baffling is done with expertise. Because it didn’t cost as much as all down, I selected this one that also has feather fibers and small feathers. I had it out for a week to see if it would leek with normal movement. It did not. We put it in a cotton duvet cover and now my Mother (who is always cold) is warm all night! ... show more

  • Great comforter but not that fluffy
Its lightweight, soft and warm.. Only thing I am not sure is how much it should fluff up as its not that fluffy. But it serves the purpose! And love the color..

  • Great product!
Size: California King Color: White/Heavyweight
I bought this California king duvet insert and I will never look back! By far the coziest duvet ever. Pro tip: always buy a Cali king insert with a king duvet cover for optimal fluffiness!

  • Affordable, poofy, love it
Size: Twin Color: Grey/Heavyweight
The cotton material is not heavy duty but it's going to keep me toasty this winter. I searched long and hard, high & low, on many different sites. I had a limited budget, but my RV has no heat & after an injury that's kept me from working, early SS says I can't work yet. I needed something to keep my dogs & i from freezing. The price for what I got was a gogodsend. Its gonna be zero tonite so arrived just in time. I am exceptionally pleased. I have had down alternative comforters in the past, but they just werent as warm. This down is certified responsibly harvested so its even more of a bargain. I bought a verybpretty duvet cover to keep it protected too. Im giddy. And warm! ... show more

  • The Heavy Weight is the ONE if you wants heavy, super super warm, down comforter
Size: King Color: Grey/Heavyweight
Yes! This one. If you want a heavy weight down comforter, this is THE one. I've had quite a few high end feather and down comforters, but this one is hands down one of the best. If you select their regular one, vs the heavy weight, I have a feeling that you'll also love that one. Great quality.

  • Did not like the feel
Size: King Color: Grey/Heavyweight
This product fluffed up nice and was quite heavy. However, the outside felt sort of plastic ky and was loud. I probably could of purchased a cover but for the price and color options, I was expecting to use as is. I returned for a different option. The color was a beautiful charcoal Grey though.
