Review: A 3-year Fart Veteran - I have been waiting to write a review on these for a few years, because I wanted to truly test them out. After buying Shreddies for 3 years I can say with confidence that they are worth it. My hubby was diagnosed with Crohn's Disease and lost over 40cm of his intestine including his colon. So, it doesn't take long before he has to go to the bathroom. This also makes his farts 10 times worse. I read a review who has the same problem, and I can confirm that people with Crohn's have way nastier farts. They are on a whole other level. As far as the effectiveness, I will tell you that they aren't 100% effective, but I don't wake up in the morning with the room smelling like hot garbage made of last night's dinner. These helped cut it down quite a bit. You have to use it exactly the way they instruct you in order for it to work properly, so while sleepy you're not likely to clench your buttcheeks before a fart. Even so, they still filter out a decent amount of stank. As far as washing, you only use cold water with baking soda for washing and high heat for drying. When they come out of the washing machine, they will stink, but when you pop them in the dryer, they stop. Be aware of not washing them with regular detergent and using softener, as it clogs the filter and doesn't work as well. Your best bet is to get a small basket that you throw them into. My hubby only wears them at night, so they last a bit longer. The more you wash them, the quicker they wear out. So, try to spread your washings a bit. I bought 4 of them. Which is $100 worth (ouch). It hurts my heart to spend that much, but those four pear when alternated can last you a whole year or two. I guess $100 every one or two months isn't too bad when you think about how much you're going to save your nose from a constant barrage of farts. If the price would changr, I would buy 10 of these bad boys, but until then, I'll keep with my 4 pair every year or so.
Review: Great product can't believe they work so well! (washing instructions in review) - THEY DO RUN SMALL! These have a different cut (like a boyshort for a woman) so if that's a weird cut for you, get the briefs or get these a little bigger.... These work by having a carbon thread woven into a sort of thicker pad that goes from the undercarriage, to the back of the brief. This pad filters out any odors and it does so VERY VERY VERY well. I am known by my girlfriend to have some of the most rank farts ever. I fart a lot and while I haven't been diagnosed with IBS or Crohns I do expell more than the average 14 a day. Anyway, these stop them dead in their tracks. I've only had them a week. The fibers that do this filtering are very fickle. Do not run these through a washer or dryer despite what the tag says. I hand washed these in cold water (in a bucket in the basement by the laundry machine) Rubbed a few tbsp of baking soda into the most heavily used portions of the garment. Hung them on a door knob to dry overnight. They still work. I imagine these will work for as long as they stay together (elastic doesn't last forever) Literally the best thing ever. If I fart under the covers, and lift them for a smell, there's NOTHING there. It's really quite incredible. P.S. I will update if they do by chance begin to fail with this same kind of washing method. Laundry detergent and fabric softener break down threads so don't be surprised if these stop working after you run them through a cycle!

### ⭐ After five hand washings....
*by M***S on February 24, 2020*

After five hand washings with baking soda and letting them air dry, as recommended by the company, these are not holding up anymore. Before that though, I couldnt believe how well they worked. But for $50 and only lasting me two months.....eh, I cant recommend these. Also, Im a 36-38 waist and the XL were pretty tight. Maybe its for "sealing" purposes. I can understand that if thats the case. Otherwise, they should add more room in the front area, if you know what I mean.
