Cool Area Sun Shade Sail 13x20 ft Rectangle - Patio & Backyard Shade

In this review of the Cool Area Sun Shade Sail 13x20 ft rectangle, the bottom line is simple: it is a practical, low-cost solution for adding reliable sun protection to patios, decks and pools. The sail is best for homeowners who want heavy shade without complex construction, and the single biggest reason to buy is its whole-piece HDPE fabric that gives consistent shading and a neat appearance. The review finds it delivers strong UV reduction and straightforward installation while offering durable corner hardware for seasonal outdoor use.

Key Features

• 100% new HDPE fabric: Provides a high shading rate and resists sun degradation so outdoor spaces stay noticeably cooler.
• 95% UV protection: Blocks the majority of harmful UV rays to protect people and furnishings beneath the canopy.
• No splicing seams: The single-piece construction improves appearance and delivers uniform shade coverage across the entire sail.
• Reinforced stitched edges: Prevents fraying and helps the sail retain its shape through wind and handling.
• Stainless steel D-rings at corners: Durable, rust-proof attachment points make it easier to secure the sail to anchors like posts and walls.
• Tolerance for elasticity: The material allows a small size variance and requires 0.5-1 ft extra for installation hardware.

Who It's For

The Cool Area 13x20 ft sail is aimed at homeowners and renters who need a quick, attractive shade solution for patios, pergolas, balconies or poolside areas. It is a good fit for people who want strong sun protection and a neat, single-piece canopy without professional installation.

It is less suitable for permanent roofing or locations with extremely severe storms; those needing a fixed structure or heavy snow load protection should consider rigid canopies or architectural shade systems instead.
