WoW Plates

Available

Weight on Webbing — lead where you need it

Weight on Webbing plates let you attach lead weights directly to any 2″ harness webbing — no pockets, no pouches, no re-kitting. Slide them on, lock them in, and trim your buoyancy exactly where it matters.

  • Fits any standard 2″ webbing
  • Secure locking — won't shift under water
  • Modular: add or remove plates per dive
  • Printed in durable PETG

Long Hose Retainer

Available

Your long hose, exactly where you put it

A triglide-based retainer that fixes your long hose firmly to your harness or belt — unlike standard bungee retainers that slide and shift. The triglide config also adds an extra D-ring so you can clip fins, a torch, SMB, or reel instead of loading up your shoulder D-rings.

  • Triglide mount — stays put, no sliding
  • Bonus D-ring for fins, torch, SMB or reel
  • Compatible with most harness webbing
  • Compact, low-profile design
