Custom Size 13ft x 21ft Turquoise Rectangle Sun Shade Sail - UPF50

In this review the Custom Size 13' x 21' Turquoise Rectangle Sun Shade Sail is evaluated for homeowners and small commercial spaces who need reliable sun protection without sacrificing airflow. The bottom line: this shade sail is for anyone who wants 95% UV blockage and a cooler outdoor area, while retaining breathability and durability. Installation is straightforward for a DIYer comfortable with basic mounting, and the customizable D-ring measurements mean the sail can be tailored to awkward spaces.

Key Features

• 95% Sun Protection: Blocks up to 95% of harmful UV rays using a 200 GSM HDPE fabric to protect people and furnishings.
• Temperature Reduction: Lowers ambient temperature by up to 15 degrees compared to unshaded areas for noticeably cooler use of patios and play areas.
• Durable Construction: Stainless steel D-rings, reinforced edges and double-layer stitching reduce fraying and extend service life under regular outdoor exposure.
• Water and Air Permeable: The canopy allows airflow and water passage to prevent pooling and reduce wind load while maintaining shade.
• Customizable Fit: Measured from D-ring to D-ring so the sail can be made to fit specific spaces, and straight-edge custom requests are available.
• Three Year Assurance: Includes a three-year assurance that provides additional confidence in material and stitching quality.

Who It's For

This shade sail is ideal for homeowners, daycare operators, and small commercial venues who need broad UV protection and cooler outdoor seating or play areas. It suits buyers who want a custom fit, prefer a breathable canopy that wont trap heat, and appreciate heavy-duty hardware like stainless steel D-rings.

Those who should look elsewhere include buyers who need a completely waterproof awning for rain-tight coverage or people unwilling to measure carefully from D-ring to D-ring; the sail requires correct spacing at corners and some planning for anchor points.

Pros & Cons

Pros

• High UV blockage provides excellent sun protection for people and outdoor furniture.
• Durable 200 GSM HDPE fabric with reinforced edges and double stitching resists fraying and heavy use.
• Easy, flexible installation that anchors to trees, roofs, walls or poles and allows adjustment for fit.
• Breathable design reduces heat and prevents water pooling in storms.

Cons

• Not fully waterproof, so it will not provide complete rain protection in heavy downpours.
• Accurate D-ring to D-ring measurements and corner gaps are required for best performance, which may be tricky for some installations.
