  • EXTRA THICK AND SUPER DURABLE. The key to an effective above-ground pool winterizing kit is the material quality. This winter pool cover boasts a 14 × 14 scrim count (the industry’s top standard) and the density of 185 GSM. Also important in pool covers for above-ground pools are the seams: poorly done, they will let dirt through. Our 24 foot round winter pool cover prevents and keeps the water inside uncontaminated until spring.
  • PROTECTION FROM SUNLIGHT AND OVERGROWING. A pool closing kit for above ground must protect the pool from UV radiation that stays high in winter. Our pool closing kit has LDPE coating on it that withstands solar UV. The BLACK UNDERSIDE of the oval pool cover won’t let the water overgrow.
  • HIGHLY RESISTANT TO COLD. You want your winter pool cover 24 ft round above ground pool protection to survive low temperatures. Unlike a simpler pool tarp, this swimming pool cover will cope with the cold as bad as −10° F (−25° C) and the heat as high as 180° F (80° C).
  • STRONG FASTENINGS FOR A STURDIER GRIP. To make sure that your pool winter cover won’t collapse, our swimming pool covers for above ground pools have a steel-core cable that goes into reinforced metal grommets, so you can consider your pool wrap neatly tucked. A specially molded winch turns smoothly and makes it easy to really tighten the cable.
  • PREMIUM SAPPHIRE SERIES. Our pool covers, pool water bags, and pool pillows for above-ground pools rank highest on Amazon for a reason: we focus on critical characteristics like sturdiness and durability, but we also like to add little extras, like the generous 4-foot overlap on this above-ground 24 foot round winter pool cover to make winterization easier for you. Pool Pillow is not included and is sold separately.
