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.

This is awesome! I eat all the foods that give you gas - every single one of 'em. Or at least all the healthy ones: beans, greens, broccoli, cauliflower, etc etc. Avoiding them is counterproductive and annoying, so I figured I'd give these a try: they are AWESOME! As far as fit - typical British underwear fit - it's like they haven't discovered modern cuts and materials - awful, especially bad if you have any sort of bum (they're super high waisted in the front and barely cover in the back), but they work, so.... I'll forgive them. In terms of size itself: I think you can just go with your US size (if you are a US M, buy M), that's what I did and they are nowhere near snug, they are 'there'. They say they may shrink a bit after wash, so I think your size is the right size. I have not yet washed them, I'll report if they stop working after I do - I'll be extremely sad. (It's obviously too expensive for single use! It's almost too expensive period - but... worth it if they keep working! :)

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.

There a little bulky but they work

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!!!!

I have question is it really work after wash because i feel its not working after first wash.

This is the first review I've ever written for Amazon but had to write this because I can not say enough good about this product. These have saved my social life! I had to take a weekend car trip in February and share a room with a woman for the weekend and I was a bit terrified. I got a pair of these and they work. Did follow the suggestion of wearing them over my underwear since they are so expensive. They are worth every penny. I have also machine washed and dried them several times and they did not lose any effectiveness. I have a couple of week long trips coming up this year where I will again spend a lot of time in a car and will share a room, so I just ordered 3 more pair. My only complaint is that they don't come in colors or hipsters.

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.

Seemed to work the first 2 or 3 times but after that, it did did not. Also, can't get odour out. Washed and soaked several times. For the price, I would NOT recommend
