The new standard in ventilation and comfort. The V-Eight 4.0™ uses Astral's patented Airescape® technology to reduce the heat and sweat typically associated with wearing a life jacket, while the Contoured Fit™ of super-soft Gaia® foam is sculpted for mobility and prevents ride-up. A high mesh back further increases ventilation and pairs perfectly with high-back kayak seats, while Easy-Access Pockets - modeled after trail running vests - keeps gear accessible. Made with a bluesign® approved recycled shell, knife storage, and an integrated whistle, this is the life jacket for those who want it all. Modern comfort, fit, performance and storage.
