HercLeon, the company that brought us self-cleaning underwear a few years back, recently went viral for launching the fifth iteration of its HercShirt, a breakthrough design that can reportedly remain smell-free for over a month, even if you don’t wash it!
The HercShirt V5.0 was designed to stay fresh for over a month without washing. It sounds preporsterous, especially in the summer, when most of us sweat a lot more under the scorching sun, but HercLeon claims that this alchemy they came up with is real!

To keep the newest HercShirt odorless for such a long period of time, the American clothing brand used seven special ingredients – copper, silver, zinc, gold, volcanic ash, and two secret ingredients – all of which were woven into the fabric, rather than simply applied on the surface. Copper, for example, inhibits odor-causing bacteria, while zinc neutralizes harsh sulfur compounds produced by active sweating. Volcanic ash absorbs moisture and external odors, acting like a porous inner sponge.
According to HercLeon’s Kickstarter pitch, the HercShirt V5.0 stays fresh for over a month, even under heavy use. And because it only rarely requires washing, it lasts a lot longer than conventional t-shirts. It may cost $79, but ti’s suppose to last you longer than 7 regular t-shirts, so it should be worth the investment.
When it becomes avaulable for shipment in early November, the HercShirt V5.0 will only be available in black, but HercLeon has already announced plans to sell navy blue, burgundy, and dark green versions.
If you feel $79 is just too much to spend on a t-shirt, even one that remains odorless for so long, you can opt for the budget option ($39), which remains fresh for 3 days of heavy use, or the standard version, which doesn’t require washing for up to 14 days.
