Men's Thermocline Spring Suit is an alternative to neoprene that is neutrally buoyant & made using recycled Ghost Gear making it actively good for the environment & part of their Ocean Positive range. The breathable fabric wicks moisture away from your skin keeping you as dry & comfortable as possible out of the water & acting much like a 2mm wetsuit but flexible & you don't need extra lead to get down. The Spring Suit is made for diving or any watersports in tropical waters to protect your arms & shoulders from the sun, bumps & scrapes as well as cool water. It can be worn by itself or you can wear it under your wetsuit to give it a thermal boost without affecting your buoyancy.
