Seawater Ballast Block
Designed for saltwater use with BN Pro, this snap-on ballast block helps offset the added buoyancy of seawater so the cleaner can maintain steadier floor contact and cleaning performance.

What Is the 52L Waterproof Backpack?
The Sublue Waterproof Backpack 52L is a large-capacity dry backpack made for carrying underwater scooters, batteries, accessories, and wet gear.
It gives users one dedicated bag for transport, storage, and water-side protection.
Fits Vapor, versatile for all.
Carry More. Worry Less.
With 52L of storage, this backpack is designed to carry larger Sublue gear, including Vapor, while still leaving room for spare batteries, chargers, towels, wetsuits, and accessories.
Designed for the last mile to the water
Comfortable Carry, Even with Heavy Gear
Padded shoulder straps and a reinforced structure help make the bag easier to carry from car to dock, beach to boat, or resort to water. It is designed for real movement, not just storage at home.
Water resistant
IPX6 Protection for Real Water Days
From rain and splashes to boat decks and beach landings, the IPX6 waterproof design helps protect your gear during water-side use. The buoyant structure also helps the bag float if accidentally dropped into water.
- Waterproof and splash-ready
- Floats for easier recovery
- Built for rain, waves, sand, and boat decks
- Keeps your gear protected between water and land
Dry–wet separation
Keep Wet Gear Away from Dry Essentials
Dedicated storage areas help separate wet items from dry clothing, electronics, towels, and daily essentials. After a dive, swim, or yacht day, your gear stays better organized and easier to manage.
- Separate soaked gear from clean essentials
- Designed for after-dive and beach-day storage
Superior protection
Built to Protect Performance Gear
Made for outdoor and marine environments, the backpack features a hard-wearing exterior, abrasion-resistant construction, reinforced stitching, and a shock-absorbing base to help protect your scooter and accessories in transit.
- Abrasion-resistant exterior
- Reinforced for repeated outdoor use
- Shock-absorbing base for added protection
- Made for decks, beaches, docks, and travel
Need the largest carrying space? Choose 52L.
Choose 52L for Vapor and Full-Gear Carry
The 52L version is the larger choice for users who carry Vapor or want extra room for multiple accessories and water-sports gear. For smaller scooter models, the 30L backpack offers a more compact carrying option.
52L — Best for Vapor and full-gear carry
30L — Best for smaller Sublue scooters and lighter trips
