Naturehike Foldable Storage Box – LingYue S Series

Twenty-five litres, which in practice is a two-burner stove, a gas canister, a kettle, two pans, plates and cutlery for four, with room for tins. The internal dimensions are 42.5 x 25 x 22.5 cm, so measure your stove against that if it is a big one.

No. It is a rigid box with a lid, not a sealed case. It keeps dust, insects and light rain off, and it will shed a shower in the back of a pickup, but it is not a dry box and should not be treated as one.

Yes, up to about 50 kg on the lid, which is the point of a rigid box. Two more loaded boxes on top is well within it. The 20 kg figure is what you put inside, and that is the one to watch, because a box loaded past that becomes awkward to lift by the side handles.

The walls hinge inward and the whole thing collapses to 9.5 cm with the lid on top. It takes a few seconds and no tools. Empty it first, obviously.

The 50 litre holds twice as much and takes 30 kg inside, but loaded it is heavy for one person and it eats more boot space folded. Most people are better served by two 25 litre boxes than one 50: easier to carry, and you can sort kitchen from everything else.

Wash it out with soapy water and let it dry fully before folding, because a folded damp box grows mould in the hinges. Keep it out of permanent direct sun when stored, since UV makes polypropylene brittle over years. Do not stand on the lid on uneven ground.
