National AllergyPremium 100% Cotton Duvet Comforter Protector - Twin Size - 66" x 86" - White - Breathable 300 Thread Count Hypoallergenic Cover - Zippered Encasement - Bedding Linen

The comforter cover came right away. it is light, works very well, and fit perfectly. I would highly recommend it. We are pleased with the look, texture, and with the protection it is giving us.

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.

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.

LOVE THIS! I would have given it 5 stars if it was a little cheaper. I paid $74 frm Amazon.PROS:- It's 100% cotton (no crinkly polyprop) with that awesome crisp feel.- Long zipper (vs buttons so your duvet doesn't hang out)- corner ties inside to keep duvet in place- Feather-proof. Especially obvious when I unzip the cover - feathers + dust flies around.- I don't have severe allergies, but it's working great for me. You can tell it has a tight weave.- extremely light-weight.CONS:- Thin. So thin you can see the color of my duvet (which is cream). Not a huge con in my book. In fact, thinking of getting another one because I love this one so much. One as a protector and 2nd one as a duvet cover that gets removed + washed. I think that will take care of the see-through factor. Wish it was slighter cheaper considering how thin it is... That's the only reason I took a star off.- Quite wrinkly out of the dryer. But I like my sheets kinda wrinkly. Makes the bed look cozy.Hope this review was helpful. They drive my decisions, so I've decided to review my purchases from now on.

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.

This protector is great. I bought it to tame the onslaught of feathers poking through my featherbed. Not only does it keep all the feathers in, but the fabric is nice enough to be your duvet cover. Best of all it has a zipper and corner ties to make putting it on, and keeping it from bunching up, a breeze. The material is thin but incredibly tight woven.

Love that I can use my down comforter now without allergies. This duvet cover works great !

The Jumbo Queen measures 96”x92” in description, but the two I got measure 90”x92”. Great fabric but much too narrow for my duvet. Returning.
