Very hard to put on the first time and I didn't even have roll bar pads. Back window was a real %#*^$. You would truly believe its way too small when installing it,really. 7mos later I still need help zipping the back window in. I haven't been through a hot Texas summer yet either, so Im sure it will still stretch some and be perfectly tight. They say the tighter the better when its new. Top is high quality, and one of the most versatile tops on the market.
