Ortlieb Duffle Metrosphere — The Waterproof Travel Bag That Belongs Anywhere

The Ortlieb Duffle Metrosphere is a waterproof travel bag designed for people who move between environments without changing their kit. In the exclusive Black Embossed nylon that defines the Metrosphere line, it carries the quiet authority of premium luggage and the resilience of outdoor equipment — equally at home in the overhead locker, lashed to a bike trailer or stowed in a sea kayak hatch. Available in 40 and 60 litres.

The Metrosphere finish is not a coating or a print — it is an embossed texture woven into the PS33 nylon itself, giving the bag a surface that catches light with restrained sophistication and holds its appearance through the wear of travel. The entire Metrosphere line is manufactured in Germany using sustainable production methods.

IP64 Waterproofing

Built from PU-coated PS33 nylon with a fully IP64 waterproof rating — completely dustproof and protected against water jets from all directions. The roll-top closure seals the main compartment without zips, making water ingress impossible during rain, road spray or transit. The sealed construction means the bag can be left outside in bad weather, loaded onto a wet boat deck or strapped to a motorcycle without concern for the contents.

Carrying System

The Duffle Metrosphere is designed for three distinct carry modes. The padded top handle provides hand carry. The detachable shoulder strap adjusts for comfortable cross-body or shoulder carry when moving through airports or stations. The removable backpack straps — stored in a dedicated zippered compartment on the back panel — allow the bag to be worn as a rucksack when both hands are needed: loading a bike, navigating a market or moving through terrain where a shoulder bag becomes impractical.

Organisation

The main roll-top compartment opens completely flat for easy packing and full access to the interior. A large external zip pocket on the front panel keeps documents, boarding passes, cables and frequently needed items immediately accessible without opening the main bag. Two internal organisation pockets separate smaller items within the main compartment.

Frequently Asked Questions

What is the difference between the 40L and 60L?

The 40L (H32×W55×D30 cm, 980 g) is sized for weekend trips, carry-on luggage where permitted, and bike-touring day bags. The 60L (H35×W65×D35 cm, 1150 g) handles a full week's travel kit, expedition gear or large loads for multi-day touring. Both share identical waterproofing, carry system and construction.

Does the Duffle Metrosphere fit as cabin luggage?

The 40L fits within the luggage allowance of many full-service airlines when compressed, but exceeds the limit of most low-cost carriers. The 60L is checked baggage size. Always verify dimensions with your carrier. The roll-top closure means the bag can be compressed significantly when not fully loaded.

What does IP64 mean for a travel bag?

IP64 means the Duffle Metrosphere is completely dustproof and protected against water jets from all directions. In practical travel terms: you can leave it on the roof of a transfer vehicle in the rain, strap it to the outside of a boat or load it onto a wet bike trailer — the contents stay completely dry. The roll-top closure seals in seconds and is the only waterproof joint on the bag.

How do the backpack straps work?

The backpack straps are stored in a zippered compartment on the back panel of the bag. When needed, unzip the compartment, pull out the straps and clip them to the bag's anchor points. They adjust for length and include a sternum strap. When not in use they stow completely inside the panel, keeping the back face clean and flat for rack or overhead storage.

Is the Ortlieb Duffle Metrosphere repairable?

Yes. All Ortlieb products are manufactured in Germany to exacting repairability standards. Replacement shoulder straps, backpack strap sets, buckles and roll-top closure components are available through Ortlieb or your local dealer. L'Hirondelle Bike Shop in Meppel can advise on repairs and spare part availability for the Duffle Metrosphere.
