Built for serious offshore miles, the Gill OS1 Ocean Trousers are engineered for endurance in the harshest bluewater conditions. Designed to pair with the OS1 Ocean Jacket, this high-fit salopette system is purpose-built for ocean crossings, offshore racing and professional bluewater sailing.
Constructed using XPLORE+® 3-layer fabric, the OS1 Ocean Trousers deliver dependable waterproof, windproof and breathable protection with fully taped seams. The outer shell is finished with Nikwax® Direct.Dry PFAS-free water repellent treatment, giving you maximum protection without compromise.
Comfort is dialled in for long watches and heavy-weather work, thanks to a super-stretch comfort back panel, adjustable shoulder straps and external waist adjustment.
