So I did an experiment with a doublenest ENO and thought I would share. Hung it between two trees in my backyard 3 years ago and never took it down. Left it hanging rain, shine, snow, 24/7 for 3 years in Northern MN. Why did I decide to take it down today? I didn't, I fell threw it and onto my ***. So if anyone was wondering how long an unattended and periodic lounging hammock from ENO might last, it's about 3 years...
