Convenient specifications considering everyday use. Innovative triple leak-proof liquid technology & easy care: Integrated with innovative bio-barrier film technology, completely preventing condensation with triple leak-proof liquid technology. It has cleared a 20,000-cycle pressure resistance test, which is 200% higher than the German-made high-quality 95A TPU JIS S 4057 (cooling product durability standard), and the durability is 60% improved compared to commercially available 90A materials. It has acquired JIS waterproof level 5 certification and is stain-resistant, so dirt such as sweat and sunscreen can be easily wiped off. Biomimetic anti-slip & precise fit: The surface treatment that applies the fluid dynamics of shark skin improves the vertical friction coefficient by 23%. Achieves a drop-off rate of 0.3% or less (3.7% for conventional products), providing a stable fit even during intense exercise. The curved design optimized for the carotid artery shape provides a comfortable fit that stays in place even during active scenes such as mountain climbing and cycling. Japanese modern aesthetics x highest safety standards: Adopts German Braun's matte etching technology to create a sense of luxury. The logo-less design emphasizes the original texture and luster of the product. Biomimetic pigment particles are directly injected into the material to maintain vivid colors for a long time. The color fading rate is less than 0.001% even after 1000 washing tests (significantly superior durability compared to conventional ink-printed products). It has acquired Japan ST safety certification and German TÜV biodegradation certification (BPA and plasticizer-free). Safe for children aged 6 and over.
