Pros

  • 20x42 sizing covers longer lap-style pools that standard 20x40 stock covers don't quite fit
  • Mesh drains on its own, no pump needed for the extra square footage
  • Same ASTM-rated structural anchoring as WaterWarden's standard sizes

Cons

  • Extended length sizing costs more than standard 20x40 stock covers

  • Mesh blocks only about 92% of sunlight versus solid vinyl
  • Larger surface area means more weight and a harder solo install
