Built to Endure. Designed to Perform.
Meet the HydraRib, one of our most rugged and technically advanced military-style watch straps yet. Inspired by the legendary Hydra from Greek mythology, a creature known for its multiple indestructible heads, this strap is engineered to offer the same relentless toughness.
Made from 100% high-quality polyamide yarn using a core-spun construction method, HydraRib sets a new benchmark in performance, comfort, and durability. The material is certified under OEKO-TEX® STANDARD 100, meaning it’s free from harmful substances and safe for prolonged skin contact, a must for those with an active lifestyle.
The HydraRib nylon material has been independently tested and confirmed to be 100% free from PFAS (Polyfluoroalkyl Substances) and fluorine compounds in accordance with EN 14582:2016 and EN 17681-1:2025 testing standards. That means no “forever chemicals,” just pure performance-ready material you can trust against your skin and the environment.
The strap’s unique three-dimensional ribbed texture is achieved through a precision close-grain weave, giving it a robust and tactile feel. It’s dyed and colour-fixed at high temperatures, ensuring excellent colourfastness that won’t fade or lint even with regular wear, washing, or exposure to the elements.
