I've had my one GTUL for maybe 4 years now. It spent 2 straight years, strung up outside, in all the weather and sun. The fabric never shown signs of failure or deterioration. In fact, I still use it most days for lunch at work.
Although a bit narrow for overnight sleeping, it's a great hammock. Can't go wrong with it. Actually my avatar picture, is of me in it, strung up at my primitive camp I lived in for 2 years.
