New Rainwear, Reborn – A Challenge to Redefine Conventional "Theory"
Redefining What Rainwear Should Truly Deliver
—True Rain Protection and Ultimate Comfort.
What Should Rainwear Truly Deliver?
Rain protection is the fundamental role of rainwear, but that alone is not enough to fully support your mountaineering adventures. True rainwear must provide both ultimate rain protection and uncompromised comfort, allowing you to move with confidence and return home safely.
With this in mind, we developed the Everbreath® Photon, featuring our proprietary Everbreath® membrane—a cutting-edge, stretchable, waterproof, and breathable fabric.
This marks the beginning of a new era in rainwear, engineered with the latest innovations to redefine what rainwear can be.
A New Level of Mobility and Comfort in Rainwear
No more compromising with restrictive, stuffy rainwear.
Designed with stretchable, waterproof, and breathable fabric, the Everbreath® Photon offers enhanced freedom of movement and a supple, comfortable fit. Its breathability lasts longer during activity compared to conventional rainwear fabrics, reducing moisture buildup and stuffiness—all while maintaining superior rain protection. This ensures lasting comfort, even during extended adventures in harsh conditions.
Additionally, we’ve incorporated a new-generation flapless, water-resistant zipper. This innovation maintains high-level water resistance while eliminating the frustration of fabric snagging during zipper operation. It also achieves a sleek, minimalist silhouette.
This is our answer to a new standard in rainwear design.
Everbreath® Photon is equipped with the next-generation water-resistant zipper, AquaGuard® Tightened, an innovation made possible through our development partnership with YKK Corporation.
The fabric is engineered with our proprietary stretchable, waterproof, and breathable membrane, Everbreath®.
The Everbreath® fabric is designed to deliver top-tier waterproof and breathable performance, engineered and tested to withstand Japan’s demanding rainy and humid climate, while also providing exceptional stretchability and durability. Its membrane features a polycarbonate-based polyurethane microporous structure, offering high resistance to deterioration from prolonged moisture exposure.
