Blue Wave BWC700 Cover Versus Dark Navy Surprising Pool Winter Benefit... Perfect Fit! We were hesitant to choose a dark navy cover for our pool, worrying about fading or excessive heat, but the Blue Wave BWC700 has proven us wrong. The material feels robust and tightly sealed, keeping ours pool debris-free over the winter. We appreciate its round design, which fits snugly with no gaps. The bronze color blends seamlessly into our yard, and the 8-year durability offers peace of mind without breaking the bank. Unlike lighter covers, ours doesn’t absorb as much sun, possibly even slightly reducing evaporation. The Dark Navy shade also hides pool mishaps better than we expected—ours looks pristine. It’s a perfect fit, and we’re impressed by the subtle benefits that come with its color and construction.
