This is either the perfect invention or it has just gone too far... depending if it actually works. HercLeon has developed underwear that is deemed to self-clean.
The undergarments don't get smelly... ever. That means you can wear them for multiple days in a row without worrying about getting a wash in between. The company says they have this special blend of Bamboo, Eucalyptus, Beechwood, and Copper fibers that help keep the underwear clean. HercLeon has named this line of underwear Kribi and each pair goes for $35. A large sum for undergarments, but I guess if you can use them for multiple days at a time then they kind of pay for themselves. And apparently they're a big hit because they are currently sold out on their site.
I do want to note that they company stated you will have to take them off for them to fully air out to stay clean. Seems too good to be true, if you ask me.
