One polo, one long sleeve, one tee.
The polo
Featherweight Supima® jersey with Hyper-Cool Jade®. Packs flat, shakes out, plane to dinner.
The long sleeve
A micro-pique button-front that reads as a shirt in a meeting and wears like a polo on the flight.
The tee
The lightest HyperNatural knit. The layer under everything, from the red-eye to the hotel gym.
Polyester is a plastic fiber that absorbs the oily compounds from your skin. Bacteria feed on those compounds to create synthetic stink.
A 2024 University of Alberta study found polyester absorbed and released the most odor compounds of five fibers tested, and held its odor intensity longest. That is the shirt you smell at baggage claim.
Plastic fibers block airflow and vent only through gaps in the knit. Recirculated cabin air and a warm gate area turn a synthetic shirt into a layer you cannot cool down in.
Conventional polyester sheds microfibers as you wear it and carries whatever finish the mill applied. Your first layer deserves the same standard as your water.
After two years of R&D at the raw fiber level, we’ve engineered the world’s most comfortable high-performance fabric
Supima® cotton
Hyper-Cool Jade®
Hyper-Chitin
Airline pilot Peter Cappio packed two HyperNatural shirts for a five-day trip. Hyper-Cool Jade® kept him cool in the cabin and the terminal. Hyper-Chitin kept both shirts fresh enough to wear again. The plastic stayed home.
“No overheating, no odor and looking classy.”
"No overheating, no odor and looking classy"
"Why don't we think more about what is directly against our skin?"
"Naturally antimicrobial. Naturally anti-inflammatory. 99.9% odor resistant. Zero BPA. Zero PFAS."
"I'm all about non-toxic fits and this brand gives me tons of options with real natural materials."
"This is for the man in your life. To nudge them in the right direction."
"The comfort and freedom of movement that I get with these clothes is absolutely awesome"
"I really like this. It's super soft and breathable."
Every HyperNatural fabric is OEKO-TEX® Standard 100 certified, so the finished textile, dyes included, has been tested against published limits for harmful substances.
Polyester does not absorb the water in sweat; it absorbs the oily compounds that carry odor, and its surface favors the bacteria that break them down. A 2024 University of Alberta study found polyester held odor intensity longest of five fibers tested. HyperNatural shirts are made with Supima® cotton and Hyper-Chitin, a natural antimicrobial from crab shells, which cuts odor-causing bacteria by 99%.
That is what it is built for. The 99% reduction in odor-causing bacteria comes from chitin in the fiber, not a finish that washes out, so a polo worn on the flight is fresh enough for dinner the next night. Hang it up overnight and pack one less shirt.
Less than plain cotton. The Pinehurst is a featherweight jersey and the El Capitán shirt is a micro-pique knit with a small amount of Creora® Regen recycled spandex, so they recover their shape when you shake them out. There is no wrinkle-resistant resin finish on any HyperNatural fabric.
Yes, on the skin. Hyper-Cool Jade® embeds jade minerals in a cellulose fiber that conducts heat away from your body, and the fabric is 20x more breathable than polyester, so the shirt runs up to 5° cooler to the touch. It will not change the cabin temperature, but it stops the shirt from holding heat against you.
For most trips, the Pinehurst Classic Fit Jersey Polo: it is the lightest polo, packs flat and works from the plane to a restaurant. Add the El Capitán Classic Fit Micro-Pique Shirt if the trip includes meetings or cooler evenings, and the Topanga Featherweight Crewneck Tee as the layer under everything. All three are made with Supima® cotton and Hyper-Cool Jade®, with 0% polyester.
The Pinehurst polo: featherweight Supima® jersey with Hyper-Cool Jade® and Hyper-Chitin. Is fresh enough to wear twice.
