The Onsen is a collapsible camping sink that packs neatly into backpacks, bike luggage and any remaining boot space for wilderness washing-up (not a separate activity – that would be weird).

  • Made from seam-taped waterproof material
  • Siliconised Cordura™ fabric is light and tough
  • Folds away into a pocket-sized pouch

Made from Cordura® siliconized nylon, a waterproof material that’s exceptionally high strength for its weight, the Onsen is fully seam-taped to hold your washing-up water in. Once filled, the water moves to the widest parts of the Onsen while the rim pops up to stop your suds from escaping.

The Onsen uses a flexible rim that pops instantly into shape when you unpack it from its pocket-sized stuff bag. We’ve also added Hypalon carry handles so you can carry your mucky pots to and from the campsite facilities/nearby stream.
