Gill OS1 Offshore Jacket

No compromise protection for those facing the toughest ocean conditions. The OS1 equips ocean sailors with a durable, waterproof, breathable and fully-taped defence against the cold ocean environment.

Utilising a new shell fabric specifically engineered by our technicians to survive the rigours of open ocean conditions, the OS1 Jacket is now lighter and more manoeuvrable.
