Sasawashi: The Japanese UV-protective textile that is healthy and sustainable

Sasawashi : Le textile japonais anti-UV, sain et durable

In a world where sun protection, comfort, and sustainability are becoming priorities, the brand Sasawashi offers an elegant and natural solution. Born in Japan, Sasawashi has developed a unique textile that combines traditional craftsmanship, textile innovation, and ecological commitment.


A revolutionary textile: Sasa Washi

The name “Sasawashi” is a combination of two Japanese words:

  • Sasa (笹): a variety of bamboo called Kumazasa, known for its purifying and medicinal properties.
  • Washi (和紙): traditional Japanese paper made from long and resilient plant fibers, such as mulberry.

By combining these two materials, Sasawashi created an innovative textile fiber, woven from twisted strips of washi paper infused with Kumazasa extract. The result? A breathable, antibacterial, odor-resistant, and naturally UV-blocking fabric — without any chemical treatment.


Natural UV protection, without compromise

Unlike most UV-blocking textiles that rely on chemical treatments or synthetic coatings, Sasawashi fabric blocks up to 98% of UV rays thanks to the very structure of the fiber and the natural properties of Kumazasa.

It protects the skin from harmful sun exposure while allowing the skin to breathe. Lightweight, soft, and absorbent, it provides optimal thermal comfort in summer as well as during mid-season.


Why choose Sasawashi for summer?

  • High level of sun protection
  • Breathable fabric that does not stick to the skin
  • Built-in antibacterial and deodorizing effect
  • Exceptional durability (machine washable, resistant to daily wear)
  • Natural comfort without irritation
