ColourTree 100% BLOCKAGE Waterproof 12' x 12' x 12' Turquoise Triangle Sun Shade Sail Canopy - Commercial Standard Heavy Duty - 220 GSM - 3 Years Warranty

[This review was collected as part of a promotion.] The sails were put up with a team effort in our front yard deck area. A few days after they were up, we had rain and quickly learned our errors. We had so much pooling on top which showed that they are fully waterproof. I waited about a month, then placed a second order for our backyard sails. I love having the choice of so many colors.
