If you're interested in learning hearing the full story, let us take you back to when the material was developed.
The Short Story of HercFiber
If you didn't read the story of how HercLéon was founded, check it out.
Just a few years ago, our founder, Wen, was in Iceland with a backpack full of stinky clothes. He had packed enough clothes, but because the smelly clothes were so close to the clean clothes in his bag, it made everything smell. Wen was upset by this problem because it meant he would have to wear smelly clothes to the clubs, and that's never a great first impression to make, especially in a country like Iceland where style and hygiene are critical. So he decided that when he returned to the U.S., he would find a way to make this problem not an issue for others that love to travel without luggage.
Initially, this meant backpacks that separated the dirty clothes and the stinky clothes, but this solution wasn't adequate, so he kept doing research. A few months later, Wen discovered that it was possible to turn metals like silver, copper, and even gold into fibers that can be weaved into clothing and improve the clothe's antibacterial properties. This discovery is what lead us to create HercFiber, a material that can be worn for days, weeks, and months without having to be washed.
What makes HercFiber better?
Before we settled on the different material combinations we use, we tested quite a few different materials. For luggage-free travel, the worst material was instantly evident to us. Polyester and cotton could not go a single day without starting to smell. On the plus side, polyester was better at temperature control than cotton, but on the negative side, polyester is worse for the planet. The closest alternative was Merino Wool, which is the most popular for travelers. Still, we decided against using it because we can't guarantee that the material will be sourced humanely.
These tests and results are what lead us to work with beechwood, bamboo, and eucalyptus instead of the more common and lower-priced materials.
How clean is HercFiber?
HercFiber, like any other material, gets smell-causing bacteria if you get very sweaty while enjoying your trips. The difference is that the bacteria don't last very long, and after a night of enjoying yourself, the shirt should have cleaned most of the bacteria -- depending on how fun and sweaty your night was. This antibacterial experience isn't the case with cotton and certainly not the case with polyester.
Now, this material has its limitations. The first being that it requires fresh air to clean itself effectively. The second being that we designed it for outdoor use, not necessarily for use as a nighttime shirt, since there isn't a lot of fresh air in the bed, so the material will not be as efficient as such an environment.
