Our Designer Series above ground solid winter pool covers are available in fashionable colors to compliment any pool or backyard décor. Constructed of the heavy-duty polyethylene material with extra material these covers extend beyond the pool size ensuring coverage of those pools with larger top rails. Edges are either self edged with double chain stitching or reinforced with a stitched on 1.5” binding preventing wear and tear. The covers’ topside has been treated to inhibit damaging ultra-violet rays and the bottom sides have been treated to prevent the growth of algae.
