Gill OS1 Ocean Sailing Bib Trousers – Waterproof, Breathable, High Visibility (Graphite XL)

Gill OS1 Ocean Sailing Bib Trousers: Performance for demanding days at sea

Engineered for sailors who demand protection without sacrificing mobility, the Gill OS1 Bib Trousers blend XPLORE+ waterproof fabric with a breathable interior. The plant-based water and stain repellent treatment helps keep spray, salt, and minor spills from leaving lasting marks, while the graphite color communicates a professional, marine-ready look.

Warmth and comfort come from thoughtful details: handwarmer pockets with brushed mesh lining invite you to rest your hands when the watch is long, and external waist adjustment lets you tailor the fit over layers. Abrasion resistant panels on high-wear zones stand up to gear rubbing and deck scuffs, while two deep thigh pockets provide secure spaces for essentials. The dedicated Marine Tool pocket, plus a shackle tool and hanging clip included, keep critical items within reach. For stability and fit, Gill added a multipoint shoulder adjustment and a stretch back panel, along with a PLB attachment point for optional safety gear.

Real-world use: from spray to deck-to-cockpit transitions

On wet days, you’ll appreciate the protection without feeling overheated. In lighter conditions, the breathable interior helps prevent overheating while allowing freedom of motion as you trim sails or steer. The high-visibility option also helps with crew coordination during early starts or foggy mornings.

Care and longevity

Maintenance is straightforward: rinse after use, machine wash at 30C, and tumble dry on low. Avoid bleaching or ironing. Dry storage is essential to prevent moisture buildup. With proper care, OS1 trousers are designed to stay looking and performing well through many journeys.
