Collection: Backpack Accessories

Both the Medium and Large Backpack Tidys are compatible with all our waterproof backpacks, including the smallest 20L size. They securely fit inside and help keep your gear organised, regardless of the backpack size.

All of our 20L and 30L waterproof backpacks are designed to fit within standard cabin carry-on limits, making them ideal for air travel.

Our larger 45L waterproof backpack also comes close to most airline size restrictions, measuring 49cm (H) x 33cm (W) x 28cm (D). While the depth slightly exceeds some airline limits, its soft, flexible design often allows it to fit into overhead compartments—especially when not fully packed.

Here’s how these sizes compare with cabin baggage limits from major UK and EU airlines (Height × Width × Depth):

British Airways: 56cm x 45cm x 25cm
– ✅ 20L/30L: Compliant
– ⚠️ 45L: Slightly over on depth

Jet2: 56cm x 45cm x 25cm
– ✅ 20L/30L: Compliant
– ⚠️ 45L: Slightly over on depth

EasyJet (with Up Front or large cabin bag upgrade): 56cm x 45cm x 25cm
– ✅ 20L/30L: Compliant
– ⚠️ 45L: Slightly over on depth

Ryanair (Priority Boarding): 55cm x 40cm x 20cm
– ✅ 20L/30L: Close fit
– ❌ 45L: Over on width and depth

Since cabin bag policies can vary depending on the airline and your fare type, we always recommend checking with your airline before travelling. Thanks to their soft structure, our backpacks are often accepted as cabin luggage—especially when not fully packed.

Yes, the OverBoard Urban 20L Waterproof Backpack includes a dedicated quick-access 16" laptop compartment with a weatherproof zip for added protection. Additionally, our waterproof backpacks are compatible with the Medium and Large Backpack Tidys, which securely attach to the back wall and support laptops up to 14" and 15", keeping them safe and organised.

Our waterproof backpcks are sealed using high-frequency welded seams and a roll-top sealing system. The roll-top design allows for a secure closure by rolling down the top of the bag several times and fastening it with a clip or buckle. This creates a tight, waterproof seal that prevents water from entering the bag, ensuring your gear stays dry even in wet conditions.

"Quick submersion" refers to our backpacks' ability to withstand brief periods of submersion in water without allowing water to penetrate. This means they can handle situations like accidental drops in water or short immersion, but they are not designed for prolonged submersion. For complete protection, we recommend ensuring the roll-top seal is securely fastened before exposing the backpack to water.

Our waterproof backpacks are made from high-quality, durable materials such as 900D recycled & eco-friendly PET fabric, PVC tarpaulin, TPU fabrics, and nylon ripstop. These materials are selected for their waterproof properties, strength, and ability to withstand harsh conditions, ensuring that your gear stays safe and dry during outdoor adventures or daily commute.

Our waterproof backpacks come with a range of features designed for convenience and durability, including high-frequency welded seams, roll-top seals, adjustable and padded shoulder straps, air-flow back panels, weatherproof zips, and side mesh pockets. Some models also offer quick-access laptop pockets, trolley sleeve compatibility, and reflective strips for visibility.

To clean your waterproof backpack, simply wipe it down with a damp cloth and mild soap if necessary. If the backpack has been used in saltwater, be sure to rinse it with fresh water to remove any salt residue. Avoid using harsh chemicals or putting it in the washing machine. For stubborn dirt, use a soft brush to gently scrub the affected areas. Make sure to let the backpack air dry completely before storing it.

Our weatherproof backpacks are designed to be foul weather and spray proof, offering excellent protection against rain, dirt, and dust. However, they are not fully waterproof like our dedicated waterproof backpacks. While they provide great protection in most weather conditions, they are not suitable for full submersion in water.

If you need a completely waterproof backpack, please check our Waterproof Backpack Collection for backpacks with full submersion protection.
