The Fuse Lightweight is ION's solution for a super lightweight drysuit. The drysuit is especially oriented towards SUP. It features high water resistance (10,000 mm) and is also breathable. Neoprene cuffs at the neck, arms and legs make it comfortable to wear, even for hours. The quality Tip-Zip provides impermeability to water and durability. Depending on the base layer, this suit is the go-to option for colder days. The Fuse Drysuit Lightweight is not recommended when kiting, windsurfing, or winging with a harness. In these cases, we recommend the Fuse Drysuit 4/3.
