This is a super lightweight option to help keep rain/snow from coming down your stovepipe and into you stove box. There is no way to keep 100% of rain/snow from coming into your stovebox unless you take the stovepipe out of the tent and fasten down the stovejack cover. But this is a pretty good option, especially for the weight/bulk.
