How quickly does this vest inflate in an emergency?

The Eyson 639 uses a 33-gram CO2 cylinder for rapid inflation that typically raises your head above water in about three seconds after activation. In addition to the manual pull, the unit includes an oral inflation tube as a backup so you can add air if needed.

• CO2 inflation in ~3 seconds for fast life-saving buoyancy
• Manual activation suited for conscious wearers
• Secondary oral tube on the left for emergency topping-up

What comfort and fit features help you wear it all day?

Built with soft, lightweight polyester Oxford fabric, the vest sits comfortably against the body and resists rips and punctures. An adjustable chest strap helps secure the fit for most adults, and the low-profile silhouette minimizes restriction while paddling or moving on deck.

• Lightweight polyester Oxford shell for comfort and durability
• Adjustable chest strap to fit a wide range of adult sizes
• Low-bulk design to remain unobtrusive during activity

Can I reuse and maintain this inflatable life jacket?

Yes — the Eyson 639 is designed for reuse. After CO2 deployment you replace the 33-gram cylinder and reset the green clip; the materials are washable and air-dryable, making upkeep straightforward for frequent users.

• Reusable after cylinder replacement and reset
• Washable outer cover; air-dry only to preserve materials
• Simple green clip system for quick reset and inspection

What level of buoyancy and user weight does it support?

The vest provides 150 newtons of buoyancy, appropriate for supporting adults up to approximately 330 pounds when properly fitted. While it aids in keeping the head above water, correct fit and conservative judgment are essential for safety in rough conditions.

• 150 N rated buoyancy for adult flotation assistance
