Hello, my tent is quite old - I'm thinking 8-10 years or so. I can't even remember when I traded in my Half Dome for the Quarter Dome, then a new addition. I'm hoping after I read REI's advice in more detail, I can remedy my issue. I can't justify tossing it for a new tent with the issues I'm having. The mesh is in fine condition, no tears, etc., so, will try to "fix it" somehow. Thank you, and Happy New Year!
