inflatable green tent on sale

The Concrete Canvas Shelter is a large inflatable tent made from a unique and highly functional material. It’s made from a canvas-like fabric that’s flexible and lightweight. However, when water is added to the material, it hardens into concrete.
The tent was created by a U.K-based company, which was originally developed for military use and also in an event of a natural disaster where sturdy shelters need to be resurrected quickly.
