TALLMAN.PROMO Protego inflatable continuous air domes are a unique, eye-catching twist on the traditional instant canopy. Protego domes are sturdy and heavy, so your inflatable stays in one place indoors or outdoors. These inflatable domes require continuous air supply (the Canadian Certified Blower is included in the price). Electricity is required, removing worry about leaks in the tent at your event. Simply plug in the air blower, attach it to the inflatable, and it is ready to go in minutes.
