1. Superior Buoyancy & Safety Compliance

• 275N Buoyancy: Provides robust flotation to keep adults (≥50kg) afloat in challenging conditions (e.g., rough seas, strong currents). Meets ISO 12402-2 (Type II) and CE EN 395 standards—certified for use in professional and recreational settings.
• Stable Positioning: The high buoyancy rating ensures rapid ascent to the water’s surface and maintains a safe, upright posture, reducing fatigue during emergencies.

2. Efficient Dual Inflation System

• Manual Activation: A large, ergonomic orange pull cord (front-mounted) triggers instant inflation via a 60g CO₂ cylinder (pre-installed), delivering full buoyancy in <5 seconds—critical for quick response in high-stakes situations.
• Oral Backup: A hidden, durable oral inflation tube allows for manual topping-up or re-inflation if the CO₂ cylinder is depleted, ensuring redundancy and peace of mind.

3. High Visibility Design

• Vibrant Red Shell: Maximizes visibility in open water, making users easily detectable by rescuers or companions from a distance.
• 360° Reflective Strips: Enhances low-light visibility (dawn, dusk, or nighttime), reducing risk in poor conditions.

4. Ergonomic & Comfortable Fit

• Streamlined Vest Style: Conforms to the body without restricting movement, enabling freedom of motion for activities like casting, boarding, or maneuvering a boat.
• Adjustable Straps: Heavy-duty waist and shoulder straps with quick-release buckles allow for a customized, secure fit (sizes S-XXL).
• Lightweight Construction: ≈750g uninflated—minimizes fatigue during extended wear, even in hot or humid climates.

5. Durable & Long-Lasting Build

• Outer Shell: Tear-resistant, water-repellent nylon fabric that withstands saltwater, UV damage, and rough use—ideal for frequent offshore adventures.
• Inflation Bladder: Leak-proof TPU (Thermoplastic Polyurethane) material, tested for pressure resistance and abrasion—ensures long-term reliability.
• Hardware: Corrosion-resistant stainless steel D-rings (for attaching tools/lanyards) and heavy-duty plastic buckles—stays secure in wet conditions.

Technical Specifications

Ideal Applications

The ES639275 is built for high-stakes water activities where buoyancy and reliability matter most:

• Offshore boating (yachts, sailboats, powerboats)
• Deep-sea fishing (commercial/recreational)
• Water sports (wakeboarding, jet skiing, kite surfing)
• Coastal cruising (rough sea conditions)
• Professional use (fishermen, marine workers, rescue teams)

Maintenance & Care

To ensure optimal performance:

1. Post-Use Cleaning: Rinse thoroughly with fresh water to remove salt/sand. Dry in a well-ventilated area (avoid direct sunlight).
2. Leak Inspection: Submerge the inflated bladder in water—bubbles indicate a leak (repair with the included patch kit).
3. Cylinder Replacement: After activation, replace the 60g CO₂ cylinder with a genuine Eyson part (ensure proper installation).
4. Storage: Deflate completely, fold gently, and store in a cool, dry place (away from sharp objects/extreme heat).
