The Aquardian Pro Shirt from Marinepool is a lycra with an integrated buoyancy chamber. The quick-drying shirt with sun protection factor 50+ is designed to offer additional safety when surfing, on the SUP board and also when snorkelling. In an emergency situation, it can be triggered manually. A CO2 cartridge then inflates the integrated buoyancy chamber. The Pro Shirt is said to have 50 newtons of buoyancy and is certified in accordance with ISO 12402-5, meaning it fulfils all the requirements for a buoyancy aid.
Available in sizes S/M for 40 to 60 kilograms, L/XL for 60 to 90 kilograms and XXL for 80 to 100 kilograms body weight. The shirt itself weighs one kilogramme and is therefore somewhat heavier than normal Lycra. The price is 140 euros.
