All our buoyancy aids have been rigorously tested and pass EN ISO 12402-5 (watersports) and EN ISO 12402-6 (paddlesport) standards. The majority of our buoyancy aids have up to 20% more buoyancy than the ISO/CE standard 50 N required. We are committed to ensuring all our products made to the highest standards possibly to ensure safety for all who use them. Please always use our buoyancy aids correctly, and wear the correct size for the participant. Look after all your equipment and replace buoyancy aids after the recommended 5 year life span, or if any elements show wear or are broken.
