Our canvas wall tents are roomy, offering sizes of up to 13 feet by 20 feet, with five-foot verticle walls (at the lowest spot). Our base model comes with more bells and whistles than the luxury model canvas tents sold elsewhere. Each tent comes with six screened windows, ventilation ridge openings, eves, and a stove jack—it even comes complete with the angle kit. Furthermore, our tent material will not rot or mold; it is naturally waterproof and boasts a stronger rip and tear strength over cotton canvas.
