OFS900 (Isotak X) Offshore Sailing Jacket.

Tested by Team AkzoNobel and Dongfeng Race Team, the OFS900™ range represents the pinnacle of ocean racing gear and features Zhik’s latest patent pending innovations. The OFS900™ range features their multilayer composite membrane fabric proved to be 4X more waterproof durable than the marking leading ePTFE ocean fabric. All garments have been engineered to have reduced seams reducing weight, maximizing flexibility and increasing durability. Going into the Volvo Ocean Race, Zhik found that ocean gear by and large lacked the ability to adapt to different weather and conditions, meaning that crews would have to carry extra gear, or compromise on the performance of their gear. They found that safety and performance was compromised as sailors experienced inhibited central and peripheral vision from protective hoods and peaks, often resulting in a “letterbox” field of view. Uncomfortable, sticky and tight latex seals that wear down too quickly. Ocean gear needed to be safer, perform better, and be more versatile and more durable.

Developed to provide a high level of protection while enhancing the sailor’s field of vision, Hydrovison® is Zhik’s new hood visor, made from a rigid & anti-fogging clear polycarbonate which provides unprecedented peripheral vision and protection. The Hydrovision® visor greatly reduces the “letterboxing” effect of traditional hoods, providing at least double the amount of vertical vision, while increasing the protection against the large amounts of water that smash directly into the face. The visor can also be unzipped and swapped out with other Zhik visor types. Patent Pending.

Biomotion reflective detailing highlights key points of the human anatomy, enabling greater visual recognition of crew members & allowing them to judge movement and direction in low light conditions. This grants valuable split seconds of response time in cases of emergency.

The result is an extremely lightweight and highly breathable fabrication with class leading levels of waterproof durability.



  • After use, rinse with fresh, clean water – then drip dry in the shade until thoroughly dry.
  • Do not store when wet.
  • After intense use or 6-12 months of casual use, wash using a detergent specifically designed for technical waterproof clothing. Follow instructions on label.


After washing, allow to dry completely in the shade and then place the garments in a clothes dryer on high heat for 15 minutes or iron fabric using medium heat (do not iron prints and do not apply excess heat to the garment seams). The application of heat will help to reactivate the water repellency of the fabric.
