I have owned 4 different SD tents before I bought the Zolo 3. I have long been a fan of SD for their quality products and excellent customer service. I bought the Zolo for a 18 day river trip through the Grand Canyon. I wanted a roomy tent that would set up and break down easily. The Zolo shines in these departments. The real disappoint came on our first rainy night. The fly went on quite easily even in the dark but leaked through the zippers. This was not a material defect but rather a design flaw.. I can't believe the designers did not test this tent under simulated rain. The thing leaks pure and simple. SD needs to go back to the drawing board on the fly. I forgot to mention the tent has great ventilation and breaths well even on hot Summer nights in the desert.
