Gill OS Performance Trousers Purpose-built for offshore conditions, the OS Performance Trousers deliver reliable thermal protection and mobility when your gear needs to go the distance. Made from smooth-faced thermal fleece with 4-way stretch, these trousers strike the perfect 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 zipper offers easy access and adjustable ventilation, while reinforced knees and seat provide added durability in high-wear areas—whether you're perched on the rail or working below deck. Treated with SHIELD® PFAS-free water repellent, they offer an eco-conscious layer of defense against spray and light moisture. Engineered for comfort and built to perform, the OS Performance Trousers help you power through cold fronts and stay focused on the next tack. Pair with the OS Performance Jacket for a complete midlayer solution. Product Care Machine Wash (30°C). Do not Bleach. Tumble Dry Low . No Iron. Do Not Dry Clean. Do not store wet.
