I tend to define a tent as a portable structure that can be put up and taken down as needed, but others think of it as any structure made out of tensile materials, held up with cables and poles. So under that definition, this Caccoon would be a tent. It does share some attributes with tents:
This 6-kilogram (13-pound) tree tent can be packed flat, but holds its shape thanks to its rust-proof aluminum ring. In any case, it's one of the least material-intensive tree tents we've seen thus far. The smallest Cacoon holds up to 220 pounds, the largest size can carry up to 440 pounds, and can be hung from a tree or from a tripod.
