Ive had my Kodiak 10x10 for 11 years using it 3 times per year in spring rains, winter rains, and summer rains. I've never had a leak that wasn't due to my error in leaving a window unzipped. My Kodiak has always been sturdy and its sewn seams are as strong after a decade of use as they were on day one. I bought mine from Cabelas online with free shipping in 2008.
