If you want to be toasty in your tent and stove shield is a must for any stove. You can have a one time adjustable size of 4/5", or 5/6". Our stove shields are made out of a flexible silicone coated fiberglass. It is flame retardant and so is the thread. The flap is made out of all the fabric choices we offer on our wall tents. This is a do it yourself project when you order it seperate from the tent.
