The new OS1 Ocean System – Beyond Tested. Ocean Proven.

50 years of innovation. Tested in our lab. Tried at sea. Proven across 5,000 miles to the Arctic and back.

The new OS1 Ocean System is our most advanced ocean-going apparel to date, setting a new benchmark in performance, protection, and material innovation for offshore and ocean sailors. Engineered for the most demanding conditions, the OS1 combines rigorous in-house laboratory testing with over 5,000 miles of real-world Arctic sailing validation by Matt and Amy aboard Sailing Yacht Florence.

In a marine-first collaboration with Nikwax, the system features a PFAS-free Durable Water Repellent (DWR) treatment, delivering industry-leading water repellence and protection.  The result is an ocean system engineered with precision and proven where it matters most — at sea.

Ocean Proven in the Arctic

To ensure the OS1 System is equipped for the harshest environments, we pushed performance beyond the lab and onto the deck of Sailing Yacht Florence – covering 5,000 miles to the Arctic and back. Matt & Amy tested the OS1 against sub-zero temperatures, punishing wind chill, and weeks of relentless exposure, and the system stood firm against everything the elements threw at it, proving itself where it matters most.

“It shuts out the wind chill and weather whilst still allowing us to feel that we can move around relatively unencumbered. It was reassuring to know it could keep us warm and dry as we increased the layers underneath when sailing further north.”

Designed for Life on Deck

The new OS1 Ocean System balances enhanced safety with ergonomic design. For maximum visibility, the range features 360° photoluminescent prismatic reflectives, including specialized glow-in-the-dark elements on the trousers. To simplify operation in harsh conditions, the system utilises oversized zips, cuffs, and storm guards, alongside a stowable face guard. Additionally, ergonomic patterning reduces fatigue during extended periods on deck.
