The Brompton Waterproof Rolltop Small is a versatile 15-litre waterproof bag designed to work just as well off the bike as it does on your Brompton. Combining a compact front bag with a practical backpack, it provides convenient everyday storage for commuting, travelling and riding in unpredictable weather.

Designed specifically around the way a Brompton is ridden, folded and carried, the Waterproof Rolltop Small attaches to the front of the bike with a quick click. Brompton's luggage system carries the weight through the frame rather than the handlebars, helping maintain stable and predictable handling even when the bag is loaded.
Once you reach your destination, the bag transforms into a backpack in seconds. Low-profile magnetic shoulder straps remain neatly tucked away while riding and can be quickly pulled free when you remove the bag from the bike. Grab handles provide another convenient carrying option when you're moving between the bike, train, office or home.
The distinctive rolltop opening allows the bag to adjust to suit your load and uses a Velcro closure to keep everything secure. An external zipped waterproof pocket provides quick access to everyday essentials without needing to open the main compartment, while a padded laptop sleeve inside helps organise and protect your tech.
Built for year-round riding, the bag features RF welded waterproof construction with an IPX4 rating. Highly durable recycled nylon materials and waterproof zippers provide additional protection against wet weather, while glove-friendly zip pulls make the bag easier to use when conditions turn cold.
With its practical 15-litre capacity, backpack functionality and weather-resistant construction, the Brompton Waterproof Rolltop Small is an excellent choice for commuters and everyday Brompton riders who want one versatile bag for both cycling and carrying.
