V-EIGHT 4.0
 
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.

AIRESCAPE® SYSTEM
Revolutionary Airescape® architecture channels airflow through the life jacket, shedding excess heat and actively regulating core temperatures.

CONTOURED FIT™
Super-soft Gaia® foam is sculpted to follow the body’s natural contours, maximizing comfort and mobility. A carved-out chest panel prevents ride-up and ensures a secure, low-profile fit.

HIGH MESH BACK
For maximum ventilation and a secure, comfortable fit with high-back seat designs.

EASY-ACCESS POCKETS™
An innovative three-pocket system inspired by trail running vests provides quick, one-handed access to on-water essentials.

BLUESIGN®
Astral is the world’s first company to make PFDs with bluesign® approved materials. V-Eight 4.0™ features a shell of 300D diamond ripstop made from bluesign™ approved, 100% recycled polyester.
