A ten-litre collapsible bucket with a carry handle. Folds flat.

Double the five-litre, and worth it if you are cooking for a group or want enough water on hand to drown a fire properly rather than kicking dirt at it.

Ten litres is about twenty-two pounds full, so you will carry it with two hands when it is loaded. That is normal for a bucket this size.

Folds down for storage like the smaller one, so the extra capacity costs you nothing in cargo space.
