The system has a 2:1 gear ratio for effortless reefing, without having to leave the cockpit.

  • ø10 mm white/blue 32/3 Polyester line for reef 1. 6+ 25 m
  • ø10 mm white/red 32/3 Polyester line for reef 2. 6 + 38 m

These were so cute, but run narrow. My daughter tried wearing them but she kept complaining they were too tight. Wish we could love them because I love how easy this brand is for my daughter to get on her feet
