Buoyancy Capacity | Open water swimming, drifting | Industry: 5kg buoyancy (ISO 9901) Base: 6kg (▲1kg) Advanced: 7kg (▲2kg) | Enhanced safety in deep water; ▲1kg improves stability for stronger currents | Heavier with higher buoyancy; may restrict mobility in shallow pools |
Material Composition | All water activities | Industry: Standard nylon Base: 3mm neoprene foam (ASTM F1958) Advanced: 5mm neoprene + UV protection (▲2mm) | Flexibility, warmth, and durability; ▲2mm in Advanced improves thermal retention | Base version may sag over time; Advanced is bulkier and costlier |
Safety Features | High-risk water sports (e.g., whitewater) | Industry: Basic buckle straps Base: Adjustable chest/neck straps (ISO 12402-5) Advanced: Quick-release zipper + auto-inflation (▲1 feature) | Secure fit reduces slipping; ▲1 feature in Advanced allows emergency deflation | Advanced requires training for quick-release mechanisms; bulkier design |
Water Resistance | Prolonged exposure (e.g., ocean trips) | Industry: 300-cycle abrasion resistance (ASTM D3389) Base: 500 cycles (▲200) Advanced: 1000 cycles (▲700) | ▲200 cycles in Base extend lifespan; Advanced resists saltwater corrosion | Heavier with layered materials; may require professional cleaning for Advanced |
Temperature Regulation | Cold-water environments (e.g., lakes) | Industry: No thermal rating Base: 3.2 TOG (ISO 9920) Advanced: 4.5 TOG (▲1.3) | ▲1.3 TOG in Advanced keeps kids warmer in cold water; Base prevents overheating | Advanced may overheat in tropical climates; Base lacks extreme cold protection |
Customization | Team/group activities (e.g., camps) | Industry: Basic logos only Base: Customizable patterns (EN 374-3) Advanced: Full-color logos + reflective strips (▲1 feature) | ▲1 feature in Advanced enhances visibility at night; Base suits casual use | Advanced customization adds 20% to cost; limited color options for mass orders |
