Very nice duvet cover
Size: Full / Queen (86x86) Style: Protector
Here’s a polished review: I really like this duvet cover. The 100% cotton material is exactly what I was looking for, and it’s perfect for the warm Caribbean climate because it feels cool and breathable. The size fits perfectly as well. I washed it and dried it in the dryer before using it, and it came out very wrinkled, so it does require ironing if you want a crisp look. Other than that, I’m very happy with my purchase and will definitely buy another one. ... show more

Finally a great, simple, quality duvet
Size: Twin (66x86) Style: Protector
I was looking for a duvet with a true quality feel. A crisp cotton that still feels comfortable. A duvet that washes and dries well, while still looking fresh and new. So far this duvet meets my expectations. Bonus, no more feathers everywhere. If I run into quality problems, I will update.

Efficient dust mites barrier
Size: Full / Queen (86x86) Style: Protector
This was my second time to purchase the product for a different comforter. I am allergic to the fragrance, dust mites, and feathers. This product does not have any synthetic scent. The material was type of cotton which is thick enough for dust mites barrier. There are ties of each interior corner to secure my down comforter which has corner loops. I washed it by fallowing the instructions before I used it. The fabric was softened a little. I have using it for two weeks and have no signs of allergy reactions. ... show more

Large and protective for comforters and blankets
Size: Jumbo Queen (96x92) Style: Protector
This comforter protector is large and is perfect to cover comforter or thick blankets that are queen size. Its materials are soft but form a firm protection. Zipper closes well and strings at corners are convenient to tie the corners of blankets. However, it does take a long time to dry after washing and it wrinkles up after drying in the drying machine. ... show more

Smell, Feel is not like cotton.
Size: Twin (66x86) Style: Protector
Hey, about 4yrs ago I bought a full size cotton duvet directly from National Allergy Supply, and i love it. This twin sized duvet I bought from Amazon arrived in no packaging, just a plastic ziplock bag. I opened the ziplock bag and felt the fabric. It didn't feel like the soft cotton duvet that I had bought before. It felt like plastic. It gave off an acrid smell. In the past, I've bought cotton T-shirts off Ebay and for the past couple years, there is often a strong smell and the fabric feels unnaturally stiffened and then becomes rough after being washed and still smells. They can't be worn without the feeling that the fabric doesn't breathe. One of them fell apart after being washed. I sought the sellers asking what was the problem. Finally one was honest. He stated they store them in plastic bags sometimes for years, that is why the smell. But it seems the plastic is embedded in the fabric. I imagine the most logical conclusion is this cotton duvet I just bought has been sitting for years in some hot warehouse until they have to dig it out of storage to ship it. ... show more

Don't buy it for the way it looks or feels.
Size: Jumbo Queen (96x92) Style: Protector
I bought this duvet far too long after I should have. I have developed allergies over the years. I have noticed that I would wake up with a stuffy nose and lots of congestion for some time now. I suspected that it had to do with my down comforter, but I was too cheap to buy an allergy protective cover because I was not sure if it would solve my problem. This cover has made a huge difference. I am waking up without being congested and I am having far fewer allergy symptoms. It was worth the purchase and of course I wish I bought it sooner. Yes the material may not feel like you expect. It is tightly woven which has also made my comforter warmer since less air is passing through. It might make some noise, but I do not notice, especially after it is broken in a bit. It also might hold some wrinkles, but mine is between my comforter and my decorative duvet. So if those things matter more than breathing better, maybe this is not for you. If your goal is to wake up with clear nostrils then don't keep waiting. ... show more

Keeps the down feathers in!!
Size: Jumbo Queen (96x92) Style: Protector
Down is hands down the best temperature regulating material. But almost not worth it because of the escaping down! They are just a headache and mess!!! This solved that problem! I now can love my down comforters. It does not interfere with breathability. It is "loud" in that it crinkles. But this doesn't bother me. It sounds "crisp" to me. This is my second one. The first, I've washed multiple times. Just gets softer and holds up well. It feels like quality materials. Zipper is fantastic! And fits great. I haven't needed to test if it's water proof. I'd say just being dense enough to keep down inside it would be naturally water resistant. It is NOT plastic. Which some water proof materials are and they don't breathe. ... show more
