Wear it for thirty days without a wash. Travel light, live longer in one shirt, and stop planning your day around when it has to come off. HercShirt V5.0 was built to handle every kind of smell, so you can finally stop thinking about the one thing nobody talks about.
It's not just an annoying problem. It's the reason you pack more, wash more, and quietly plan around the smell.

You pack five shirts for a five day trip. Three for the days that get warm. One for backup. The whole bag gets built around the assumption that any shirt is one wear away from the laundry pile.

Most people wash a t-shirt after every wear. That's hours of your life every week, water and energy you can't get back, and a slow march toward the shirt looking older than it is.

Workout clothes. Work clothes. Dinner clothes. Three changes for one day, all because the first shirt couldn't handle the next thing on your calendar.

The trail you skipped because the day was too long. The dinner you went home before. A small life of small accommodations, all because of what your shirt couldn't do.
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 in your wardrobe. The version we've been working toward since the start, finally ready.

Each one woven into the fabric for permanent performance, not a spray on or coating.

Why HercShirt handles bacterial smell better than anything else in your drawer. Trusted on hospital touch surfaces and on the International Space Station.

Silver brings antimicrobial properties used since ancient civilizations. Zinc handles sulfur and the sharp note of a hard workout, and tends to take inflammation out of skin along the way. Gold is the catalyst, a small amount doing oversized work to accelerate everything else.

Volcanic ash traps environmental smell like a sponge and emits far infrared, which is why HercShirt tends to feel a little fresher than it should. Vitamin E quietly stops skin oils from going rancid while looking after your skin in the background.

A specialized fiber engineered in Japan, where this kind of textile science has been quietly happening for decades. A plasma machine reshapes the surface chemistry so the fiber binds to ammonia molecules on contact, handling the sharp post workout sting.
HercShirt was built for travelers first. The fabric handles odor so good that a single shirt can be worn for thirty days or more without developing the smell that builds up in regular cotton or polyester after a single wear.
This changes how packing works. One shirt covers a month abroad. A carry on bag holds an actual trip's worth of clothing. The laundromat search or sink washing at a vacation goes away.

The same engineering that handles a thirty day trip also handles a sixteen hour day at home. HercShirt was designed to perform across the gym, the office, and dinner without needing to be changed in between.
Most shirts start to smell within a few hours of activity, which is why people change clothes between workouts and meetings. HercShirt handles the bacteria, sweat, and skin oils that cause that smell at the source, so the shirt that started the day at 7am still feels right at 9pm.

• Thirty days, one shirt.
Most cotton shirts start to smell within hours. HercShirt handles the bacteria and sweat that cause odor at the source, so the same shirt can be worn for thirty days or more without needing a wash.
• Move between activities without thinking about it.
Most people need to change clothes between the gym, the office, and dinner. HercShirt removes that problem. One shirt handles the 7am workout and the 9pm dinner without picking up smell in between.

• Less laundry.
The average person washes a t-shirt after every wear. HercShirt typically goes weeks between washes. Hours of time back, less water used, a shirt that lasts much longer than one being washed every day.
• Daylight refreshes it.
UV light from regular daylight reactivates the antimicrobial elements in the fabric. Time spent walking outside in normal sun is essentially refreshing the shirt between wears. No special care needed.

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 closet.’
• 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 tested HercShirt against the three fabrics most shirts are made of. Here's how well each one handles the types of smell on a score from 1 to 10.

We created the HercShirt with one purpose only: Odor Resistance. Along the way, we developed it to also be an overall amazing shirt.





Our fiber is the only fabric in this comparison engineered with a 10 micron count, infused with various minerals. That's not a marketing angle, it's why the dots look the way they do.

During a trip in Iceland, 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. Now we've solved it. HercShirt V5.0 is what that question turned into.
