This is the Flowclear Solar Cover by Bestway, meant for round pools measuring 3.66 metres across. The cover itself measures 356 cm, so it is a little smaller than the pool and lies freely on the water surface.
It is made of blue polyethylene with air pockets in it - the bubble pattern you can see in the photo - which is what makes it float on its own. You lay it on in the evening and roll it back in the morning. The sunlight that passes through helps hold the warmth in the water, according to Bestway, and in the meantime leaves, insects and dust stay on the cover instead of in the pool.
Bestway states that it fits round Steel Pro, Steel Pro MAX and Hydrium pools of 3.66 m and Fast Set pools of 3.66 and 3.96 m. A storage bag is included, handy for keeping the cover packed away out of season.
One thing to watch when you look at the photo: it shows the cover on a pool, but what you order here is the cover alone. The pool, the frame and the pump are not included.
