Turquoise Rectangle 17ft x 18ft Sun Shade Sail - UPF50+ Cool Canopy

Our review looks at the 17' x 18' Turquoise Rectangle Sun Shade Sail, a custom-size canopy aimed at homeowners and small-business outdoor spaces that need heavy-duty UV protection without a permanent structure. The bottom line: this shade sail delivers reliable 95% UV blockage from a sturdy 200 GSM HDPE fabric while staying breathable and water-permeable, making it a practical choice for patios, play areas, and commercial seating where cooler, protected shade is the priority.

Key Features

• 95% Sun Protection: The 200 GSM HDPE material blocks up to 95% of harmful UV rays to keep shaded areas safer for skin and furnishings.
• Temperature Reduction: The sail can lower ambient temperature by as much as 15 degrees compared to unshaded spots, creating a noticeably cooler environment.
• Durable Construction: Reinforced edges, stainless steel D-rings and double-layer stitching resist fraying for longer life under sustained use.
• Water and Air Permeable: The fabric allows airflow and sheds light rain rather than pooling, reducing wind load and water stress on anchor points.
• Customizable Fit: Made to order from D-ring to D-ring so the sail can be tailored to nonstandard layouts and to achieve straight edges on request.
• Three-Year Assurance: A three-year assurance gives extra confidence in the material and workmanship for typical residential and light commercial use.

Who It's For

This shade sail suits homeowners, cafes, childcare centers and small commercial venues that want a removable, flexible canopy offering strong UV protection and ventilation. It is especially useful where a fixed pergola or awning is impractical but a durable cover is required for prolonged outdoor use.

It is less suitable for locations that need a fully waterproof roof for heavy, persistent rain, or for installations with extremely limited mounting options where precise D-ring-to-D-ring measurements and corner gaps cannot be achieved.

Pros & Cons

Pros

• High UV protection with effective temperature reduction for comfort in direct sun.
• Heavy-duty 200 GSM HDPE fabric with reinforced stitching and stainless hardware improves longevity.
• Custom sizing and color options help the sail blend into landscaping or commercial decor.
• Easy to install on trees, posts, walls or roofs when measurements and corner gaps are followed.

Cons

• Not fully waterproof; heavy downpours will pass some water through rather than provide total rain protection.
• Proper fit requires careful D-ring-to-D-ring measurement and attention to recommended corner gaps during installation.

Our Verdict

Frequently Asked Questions

Is this shade sail waterproof?
The fabric is water and air permeable, so it sheds light rain but is not designed as a fully waterproof roof during heavy downpours.

How should I measure for a custom order?
Measure from D-ring to D-ring for the exact fit and leave at least a 0.5 ft gap between each D-ring and its mounting pole, or reduce each side by 1 to 1.5 ft if needed.

Can it handle high winds?
Customers report the material and reinforced stitching perform well in high winds when the sail is properly tensioned and mounted to strong anchor points.
