The Science Behind HyperNatural

Yes. Polyester is a synthetic polymer made from petrochemical inputs. In apparel, polyester, nylon, acrylic, and spandex are commonly grouped as synthetic plastic-based fibers.

That is not a responsible claim. The better claim is that synthetic clothing can be a source of chemical and microfiber exposure, especially when worn against the skin during heat, sweat, and friction. Long-term disease outcomes from wearing synthetic activewear specifically need more human research.

The concern is the combination: plastic fibers, dyes, PFAS treatments, bisphenols, flame retardants, antimicrobial finishes, heat, sweat, friction, and long wear time. Activewear is not just sitting in your closet. It is rubbing against sweaty skin.

Some studies suggest this is possible for certain chemicals under lab conditions. University of Birmingham researchers found that chemicals leached from microplastics could be absorbed through skin models, and a 2024 PFAS study found dermal uptake for certain PFAS using 3D human skin models. (University of Birmingham)

Sweat and skin oils can increase the migration of certain chemicals from plastic materials. That is why workout clothing, underwear, base layers, and sleepwear matter more than a jacket you wear occasionally. (University of Birmingham)

No. That would be too broad. The issue is not simply “synthetic equals toxic.” The issue is that plastic-based textiles can involve chemical additives, finishes, dyes, and microfiber shedding — and consumers often have no clear label showing what is actually touching their skin.

Jade is a mineral material studied for far-infrared radiation properties and skin-related cosmetic applications. HyperNatural uses jade minerals to support cool-touch textile performance. We should not claim jade clothing treats inflammation or heals skin unless tested directly on HyperNatural garments. (PubMed)

Hyper-Cool Jade® is lab-tested for cool-touch performance. In SGS Qmax testing, it measured 0.13 W/cm². Qmax reflects cool-touch sensation when the fabric meets your skin — not a medical claim about lowering core body temperature.

Chitin is a natural biopolymer found in crustacean shells and other biological sources. When converted into chitosan, it has been widely studied in textiles for antimicrobial and anti-odor functionality. (Sage Journals)

No. For apparel, antimicrobial should mean the fabric has been tested to reduce specific bacteria on the textile. It does not mean the shirt prevents infection, treats skin conditions, or protects your body from disease.

OEKO-TEX STANDARD 100 means textile components have been tested against harmful-substance criteria. It is a strong consumer safety signal, but it does not mean the product is “chemical-free.” (OEKO-TEX)

bluesign focuses on safer chemistry, responsible production, and input management across textile production. For HyperNatural, be specific about what is bluesign approved: chemical input, yarn, fabric, mill, or finished product. (Bluesign)

Supima supports premium cotton authenticity and traceability. It is not the same as a harmful-substance certification, but it helps prove the quality and origin of the cotton input. (Supima)

Start with the clothing that touches your skin the longest and gets the hottest: underwear, workout shirts, base layers, sleep shirts, and travel tees.
