Purpose-built for life offshore, the OS Performance Trousers deliver dependable thermal protection and mobility when conditions demand more from your gear. Crafted from smooth-faced thermal fleece with 4-way stretch, these trousers offer a unique balance of warmth, wind resistance, and unrestricted movement—ideal for long days on deck or layered under foul weather gear.
A 2-way YKK® front zip ensures practical access and ventilation, while reinforced knees and seat enhance durability in high-wear areas, whether you're perched on the rail or working below deck. Finished with a SHIELD® PFAS-free water repellent treatment, they offer an environmentally responsible barrier against spray and light moisture.
Engineered for comfort, built for endurance—the OS Performance Trousers are your go-to for pushing through cold fronts and staying ready for the next tack.
Pair with the OS Performance Jacket for a full Midlayer solution.
