Instructions call for the temps to be above 70 degrees. Well its Seattle in February and I couldn't wait months
. They also suggested warming top indoors for an hour or two, but I only had a short window before the next rain so I went against thier advice and installed it right out of the box in 50 degree weather. It as a bit tight as expected, but the only real trouble was actualy the rear window. It was a bit of a struggle and I ended up breaking the tab on the zipper. No worries and I dont blame them. I threw on some longer cord and got it zipped up. It fits nice with no loosness and everything lined up as it should. Not as thick as the sailcloth it replaced, but I am very satisfied for the price. Went for an hour drive on the freeway and It may be louder, but its hard to say. I think I may just be convincing myself its louder because I thought it would be. Any ways, its a soft top jeep and really its not an issue with me. It certainly wasnt flapping or anything. All in all I would buy again. even if it give up after the three year warranty I'll probably just buy another.
