One shirt. Thirty days. No laundry. The HercShirt V5.0 is the first shirt engineered to handle all seven types of smell, so it stays fresh through 18-hour days and month-long trips without a wash. The HercShirt is built for travelers, minimalists, and anyone who values their time.
It's not just an annoying problem. It's the reason you pack more, wash more, and plan around the smell.

Ten shirts for a seven day trip. The carry-on is now a checked bag. Your vacation starts off at baggage claim then stressing about how to get your bags to the hotel. All this hassle because of shirts that smell.

Loading, washing, drying, folding. A few hours a week of your life, every week, for the rest of your life. Time you'll never see again is wasted because of shirts that smell.

The loss of confidence when you smell your shirt. The person across the room you don't walk over to. The seat you don't take on a packed bus. Social stress you experience all because of shirts that smell.

On a trip, you can't just change plans or extend your trip. When at home, you can't just go from gym to work to dinner. Your life is less flexible all because of shirts that smell.
Almost ten years of obsessing over what makes shirts smell, and what could be done about it. Five generations of prototypes. Thousands of conversations with customers in over a hundred countries. We finally got it where we wanted it.
The next generation of textile technology.
Built from seven of the most powerful elements in the universe. Designed to neutralize all seven kinds of smell. Engineered to last a decade. The version we've been working toward since the start, finally ready.

Made In 3 Versions:
· Max - Actually insane and unnecessarily powerful.

· Basic - Easily outperforms merino wool.

Woven into the fabric for permanent performance.

Copper kills bacteria on contact, which is the main cause of body odor. The same reason hospitals use it on touch surfaces and the International Space Station uses it in their water systems.

Silver covers a broader range of microbes that copper does not catch on its own. Zinc neutralizes the sulfur compounds released during a hard workout and tends to calm skin inflammation. And a small amount of gold accelerates the work of the other two.

Volcanic ash absorbs environmental smells the way a sponge absorbs water. We utilize it in our fiber so it can take care of smoke, food, and airborne odors that cotton holds onto for weeks. On top of that, it helps regulate the temperature of the wearer so you can be more comfortable in all environments.

The last two are our secret sauce. We'll only say this much: they involve vitamins and some seriously advanced Japanese technology. Knowing how all seven work together is what took almost ten years to get right, and it's part of what makes HercShirt hard to copy. You'll feel all seven at work. You'll just have to wear one to find out.

Most cotton shirts start to smell within hours. HercShirt handles the bacteria, sweat and oils that cause odor at the source, so the same shirt goes thirty days or more without a wash.
Now, being honest, thirty days is just the number we're comfortable printing. Back in 2019, the V2.0 of our shirts was worn around 100 days straight with no smell issue. That was a version from seven years ago. V5.0 is on a whole different level entirely. So think of thirty days as us being humble.

The average person spends a few hours a week on laundry. Loading, waiting, drying, folding, repeating. Over a year that adds up to entire days of your life spent managing clothes that smell after a single wear.
HercShirt goes weeks between washes. The same shirt you wore on Monday is still fresh the following week, no laundry cycle in between. Less time at the machine, more time doing the things you actually want to do.

You spent thousands for this trip. You blocked off the time. The whole point was to relax and have less on your plate. Not to check bags, wait at the carousel, fight for taxi trunk space, or waste vacation time doing laundry.
With HercShirt, all of that is in the past. HercShirt was built for travelers. One shirt is enough for a week or month. Change plans on a whim and never wonder if you packed enough. Your vacation will be about leisure, not luggage.
Whatever your plans, HercShirt is up for it.

The same engineering that handles a 30 day trip handles an 18 hour day. With the HercShirt, you can go from the gym to the office to dinner, without changing in between.
Most shirts start to smell within hours, which is why people segment their day around their clothes. HercShirt handles smell at the source, so the shirt you put on at 7am still feels right at 9pm. No mid-day change and no second-guessing how you come across to others. Just one shirt and one less thing on your mind, all day.

Here's an email a customer sent us about our 2020 V1.0 underwear.
Keep in mind, underwear takes far more friction, sweat, and wear than a shirt ever will, which is what makes this feedback so telling. If our V1.0 underwear survived six years of daily wear with almost no breakdown, imagine what V5.0 HercShirt can do.
We built the V5.0 to last decades, not days. Few shirts hold up like it, so you can buy one and wear it for years without worrying about a replacement.

Here's something worth knowing: women's noses are built differently. A study counting the brain's smell center found women have around 3.4 million more smell neurons than men. Nearly double.
So here's the uncomfortable truth. You might think your regular shirt smells good enough for a second wear. The average woman's nose might vehemently disagree.
That's why we built HercShirt to meet the standard of women's noses. So you can walk around with confidence even on day 30 of wearing the HercShirt.

We could say more, but if you're ready to join the list, leave your email and we'll send you an email when HercShirt is ready for you to get one.
Less time wasted, less luggages, more confidence and more adventures. All of those benefits comes from solving one problem most shirts ignore: Smell.
HercShirt is engineered to handle smell from the fiber up like never before.
Most people think of smell as one thing. It's actually seven different chemical processes:
• Microbial. ‘The locker room.’
• Sulfurous. 'The onion.'
• Fungal. ‘The damp basement.’
• Oxidative. ‘The old people smell.’
• External. ‘The campfire.’
• Nitrogenous. ‘The hard workout.’
• Hormonal. ‘Stress sweat.'
Other fabrics handle one or two of these by accident. HercShirt handles all seven on purpose.


We compared the HercShirt V5.0 against the three fabrics most shirts are made of, scoring each one across the seven types of smell using our SPR rating, the Smell Protection Rating, on a scale from 1 to 10. The higher the score, the better the fabric handles that kind of smell. The overall row at the bottom averages all seven categories.
The HercShirt V5.0 SPR rating is based on the version:
Max - 9.4
Standard - 6.3
Basic - 4.7

Each engineered with a different number of elements. The higher the SPR (Smell Protection Rating), and the more types of odors the shirt can handle and the longer it can stay smell free.

Infused with one element. The budget-friendly option. A solid step up from a regular cotton t-shirt and noticeably better than merino wool, but only slightly. Smell free up to: ~5 days of continuous wear.

Infused with two elements. The right balance of performance and value, and what most travelers reach for first. Smell free up to: ~10 days of continuous wear.

Infused with all 7 elements. Designed to handle all seven kinds of smell across thirty plus days of continuous wear. Smell free up to: ~30 days of continuous wear.

Thank you for taking the time to check out the result of almost 10 years of my life.
This journey all started during a trip to Iceland in 2017, I started asking why clothes smell and do they have to. Nobody had real answers. It took years of late nights, dead ends, and questionable looking prototypes to figure it out.
Finally, almost 10 years later, we've answered that question with the new 5th release version of the HercShirt.
