  • Float chamber: 400gsm - 610gsm PVC
  • Reinforcement:
    • High tensile webbing (2T breaking strength)
    • Structural reinforcement layers
  • Connectors:
    • Mechanical interlocking connectors
    • Marine-grade skirt connection system
  • Ballast: 6mm chain (continuous pocket)

Structural Enhancements vs Class 1
