Thanks Matt, This was a 25 mil Doughboy expandable overlap liner. The 20 mil expandable goes in just as nice. When it comes to expandable, Doughboy truly does have a superior product. These liners can be installed flat bottom as easily as expanded. That means the liners are not oversized, they expand up to 2’6” to fill a deep area of just about any size. That is a big part of the magic to a wrinkle free deep end installation.
