Marine Silicone upholstery Powered By SiO Technology™

All 2024 models now feature upholstery material made from 100% SiO Silicone making it virtually maintenance free.

So what exactly is SiO Silicone? SiO is a very pure form of silicone which, unlike conventional marine seating, is free of chemical additives. SiO’s angular resin technology offers enhanced durability, robust scuffing and scratch resistance, and the softest and most comfortable marine seating surface available today.
