The most popular product in their line is the 10x10 Instant Slant Leg Tent with a blue canopy top. It is made with a steel construction frame and polyester material for the canopy, which is in line with just about every shade tent on the market today. One thing we love about Ozark Trail canopy tents are the accessories that can be added to the shelters. The rotomolding process entails heating plastic pellets which coat the interior of a mold while it is spun around in a number of different directions at a very consistent pace. The mold is kept on the move during both the heating and coating phases as well as the cooling phase. So, I have to say that I was really surprised with how this test turned out. You can see from the images below that there was consistent ice melt, however two of the three were better performing.
