Backpack Bag for Scooter and Bike TNB UMWaterBag2 — Waterproof Roll-top, 25 L, Grey

TNB UMWaterBag2 is a waterproof roll-top backpack designed for scooters and bicycles with a 25 L capacity. Built for urban mobility, it combines backpack and transport-bag functionality to protect personal items from rain and splashes while commuting, running errands or taking short trips. The roll-top closure and waterproof materials help keep clothing, electronics and small tools dry during everyday use.

Advantages

The bag offers a straightforward waterproof design with a roll-top closure that adjusts capacity and seals out moisture. A dedicated padded compartment fits tablets or laptops up to 16 inches while internal and external pockets help organise keys and small items. Lightweight materials and shoulder straps allow comfortable carry on short commutes, and robust fabrics resist wear from frequent urban use.

Suitable for

• Daily urban commuting by scooter or bicycle
• Short trips and errands where weather protection is needed
• Carrying a tablet or compact laptop and small personal items
• Transporting tools, change of clothes or groceries in wet conditions

When it may not be suitable

The roll-top waterproof construction is effective for splashes and rain but is not recommended for prolonged full immersion in water. The 25 L capacity suits day-to-day needs but may be insufficient for extended trips requiring bulky gear or multiple large items.

Key specifications

• Capacity: 25 litres
• Closure type: roll-top with buckle and waterproof zipper elements
• Materials: textile body with mesh details, polyester (PET) and waterproof-coated layers (PVC finish)
• Carrying system: adjustable shoulder straps
• Device compartment: padded pocket for tablets/notebooks up to 16" (40.6 cm)
• External organisation: front pocket and key pocket

How to use

Open the roll-top, place items inside and fold the top down to compress the load and engage the buckle to form a weather-resistant seal. Use the padded compartment for a tablet or compact laptop and place small items in the front or key pocket for quick access. Adjust shoulder straps to distribute weight comfortably for short commutes or carry by hand when loading and unloading.

What to consider before purchase

• Confirm 25 L capacity meets your daily load requirements
• Check tablet/laptop dimensions against the 16" padded compartment
• Consider that the bag protects against rain and splashes but not prolonged submersion

Usage recommendations

For best results, roll the top tightly and secure the buckle every time it may be exposed to rain; store fragile electronics in the padded compartment and avoid overfilling to maintain the waterproof seal and comfortable carrying balance.
