The Gill OS3 Coastal Cruising Jacket delivers the freedom of coastal sailing with the reassurance of offshore-grade protection. Designed to bridge the gap between relaxed inshore cruising and longer offshore passages, it offers the perfect balance of comfort, performance and dependable weather protection — without the bulk of full ocean kit.
Built using XPLORE® 2-layer waterproof and breathable fabric, the OS3 keeps wind and spray firmly out while allowing moisture to escape during active sailing. A SHIELD® PFAS-free water repellent finish adds eco-conscious protection, while fully taped seams and a double storm guard over the anti-corrosion YKK zip ensure watertight performance where it matters most.
Designed for sailors who expect more from their coastal gear, the OS3 features a packable hi-vis hood, a thermal fleece-lined collar, and adjustable double cuffs with PU inner seals for all-day comfort in changing conditions. Practical storage and adjustable detailing make it a reliable companion whether you're cruising between bays or heading beyond the horizon.
Ideal for: Coastal cruising, inshore sailing, weekend passages and light offshore use
