Shreddies USA Flatulence Filtering Women's Hi-Waist Briefs

These work well! Don't have to wash very often if you wear another pair of undies under them. Have to buy the special crystals to launder them.

They are very well made and work BUT… if you have to go through the millimeter wave scanner at the airport, know they will show up on the screen as a big red square on your crotch! Not doing that again! 🤣 So embarrassing!!!!

Opening the box, I was expecting more because let's face it, this is an expensive pair of underwear. I was hoping it would have a better wrapping. Instead of a clear plastic box and a plain purple paper explaining this underwear. I took it out the box and it is hideous. It looked like an underwear with built in padding: like an overnight pad. The materials listed are modal jersey fabric sandwiching the "activated carbon cloth" for the middle which also makes up the rest of the underwear. Seriously for an expensive pair, why couldn't they use something else that's much more durable and breathable like I don't know- COTTON material? I am a vegan with ibs so I was desperate and succumbed to this. The reviews online with the videos on YouTube, heck! Even the reviews on here gave me hope that perhaps this is the answer to my prayers- well it's not! Bought two shreddies and I've worn each underwear the whole day and let me tell you. They didn't work. The scent of my flatus seeped through and in seconds reached my nose and those who were around me. Mind you, I was also taking chlorophyll and devrom pills so my flatus is supposed to be odorless. I had one of the worst stomach pain episode accompanied by gas and this test of odor was not passed by Shreddies, Chlorophyll, nor Devrom all taken together. After just one day each of the shreddies, because the makers did not use a good quality material and instead used something cheap, the Shreddies after one day had holes on the edge where it holds the activated carbon part to block the odor. The box says "the fabric remains 2-3 years providing the care instructions are followed correctly" , it's funny because it didn't even last a day and it's already falling apart. Seriously don't waste your time, this product is not worth it.

I've been using Shreddies for a couple years and they work great, especially when they're brand new. I have noticed a decrease in effectiveness with each subsequent washing (as recommended in soda crystals aka Sodium Carbonate, cold water, gentle cycle or hand washing; line or hang drying). I wear over disposable underwear due to incontinence caused by colorectal cancer, so I don't wash until absolutely needed. I've found that I need to buy them a little small, otherwise they don't work for me. The odor needs to be "locked in" by snugness around the legs and waist. If the Shreddies are nice and comfy, they won't be as effective. Several folks have mentioned wanting colors other than black, and multi-packs. If you order directly from the company in the U.K., you can order in white or beige as well as black, and in multi-packs of 3 and maybe even 6 (it's been awhile since I ordered mine). With the current exchange rate of GBP (pounds sterling), it might even be cheaper to get them from overseas! You can find their website online. As a final note, due to my cancer I have no sphincter control so don't even know when I've had a BM, and I can tell you that I've come home with a full diaper of doo-doo, but with Shreddies I've had no idea I'd even had an accident. Before I found them I couldn't leave the house or be around anyone other than immediate family, and even they weren't too thrilled with my presence. I have so much more confidence and a brighter outlook since discovering Shreddies. As long as I can afford to, I will buy them at any price!

A little tight in the waist. Get a larger size.

I’m disappointed that the size was so different than the ones I have bought for years. These are both medium. The top one was the older pair I bought. The new one rides higher on waist and the crotch hangs lower . Before they changed the design I would have given them a five star. I didn’t return them because I had already worn them.

I bought these because every time that I fly I get super gassy. It is quite painful to hold it in and going to the restroom every ten minutes is annoying. Gas X doesn’t even help. I read the reviews of this product and decided to give them a go. Once I got through security I went to the restroom to put them on. Do not wear them through TSA or you will get a pat-down (I forgot on The way home). Sure enough 2 hours in to my 10 1/2 hour flight GAS! I let it rip and not a scent! Plus, the underwear helped muffle the noise and, with the airplane noise, nobody could hear it. I was cutting the cheese all the way to Paris and was completely comfortable as were the unassuming passengers next to me! I would recommend wearing them over you regular undies and don’t wear tight pants because it appears like a big ol pad. Well worth the money!!

This product is a lifesaver! Since my gastric bypass surgery I have been troubled by gas. To say I am embarrassed is a huge understatement! There's nothing to be done about the noise of a gaseous emission but the smell is worse. I flew 16 hours and with these panties never smelled a thing! I forgot to not wear them through customs and I set off the alert and I had to be searched! Luckily it was a woman who searched me and I explained that I was wearing charcoal. She asked where she could get a pair! Get these,! You won't regret it! Trust this world traveler!

If you are anxious about odour, these defiantly work. Very expensive, but worth every penny. I wear them outside my under garment to save from washing so often.
