i make my own stovejacks that are heavier and much more durable than the silicone welding cloth that commercial jacks are made from. i use ykk waterproof zippers.... my warranty is unconditional lifetime even if you tear it. burn holes included. i know how to fix and replace everything on the tents. i taught myself this business. noone showed me how. i do it the way i need it and i use the hell out of the stuff.
