It is made with polyurethane-coated nylon (think tent weather fly) with the clear plastic viewing window made of thermoplastic polyurethane. There is reflective tape sewn into the upper corners where the vents are co-located. The install (if you can even call it that) is simple - it fits using a combination of elastic and velcro - think triangular bedsheet.
I also like this canopy because it mutes out the sounds of my complaining and crying kids. Hey, its not my fault they don't heed my warnings about it being 0 degrees Celsius outside and still prefer to wear their princess skirt. The acoustics in there is probably pretty good, I can only imagine what surround sound crying sounds like for the adjacent kid.
Like all nylon materials exposed to the weather, they need to be treated once a season with either a silicone-based spray or something similar to retain that DWR. Its that DWR that enables the water droplets to bead and just glide off - if you run fast enough, that shit'll just hit you, so wear gore-tex.
My recommendation is that, IF, and that is a big IF...you are a hardcore outdoors person rain or shine, or just want to look the part, go ahead and get this piece, you will not be disappointed. If you can't afford the one or two hour's wage to get this piece of kit, a $0.25 lawn bag works just as well. It just looks a little more ghetto.
