17ft x 20ft White Rectangle Sun Shade Sail - UPF50+ Heavy Duty

In this review the 17' x 20' white rectangle sun shade sail is evaluated for homeowners and small commercial patios that need strong, custom-fit sun protection. The bottom line: this sail delivers reliable UV shielding and temperature reduction in a heavy-duty, customizable package and is best for users who can measure D-ring to D-ring and plan a secure installation. The review highlights material quality, ease of installation, and durability rather than decorative features, so buyers looking primarily for style over performance should note that function leads the design here.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays for safer outdoor use.
• Temperature reduction: The shade sail can reduce surface temperature by up to 15 degrees, making patios noticeably cooler under direct sun.
• Commercial-grade durability: Reinforced edges and stainless steel D-Rings with double-layer stitching resist fraying and extend service life.
• Customizable fit: Made to order from D-ring to D-ring measurements so the sail adapts to irregular spaces or nonstandard mounting points.
• Permeable design: The water and air permeable weave sheds some wind load and moisture rather than acting as a solid sail in storms.
• Three-year assurance: The included assurance covers manufacturing concerns, giving added confidence in material and workmanship.

Who It's For

The shade sail is ideal for homeowners, cafes, and poolside areas that need robust UV protection and a cooler outdoor area without a permanent structure; its custom sizing makes it useful for odd-shaped patios or where precise D-ring measurements are available. Installers who value long-term durability and reduced fading will appreciate the heavy 200 GSM HDPE and reinforced construction.

It is less suited to buyers who want a purely decorative canopy or who cannot provide accurate D-ring to D-ring measurements for a made-to-order product. Also, anyone expecting a fully waterproof awning should look elsewhere, since the fabric is water and air permeable rather than fully impermeable.

Pros & Cons

Pros

• Excellent sun protection and temperature reduction thanks to the 95% UV blocking fabric.
• Sturdy construction with stainless steel D-Rings and double-layer stitching for long-term durability.
• Custom sizing lets the sail fit specific areas precisely when measured correctly.
• Easy and flexible installation options to attach to trees, roofs, walls, or poles.

Cons

• Not fully waterproof due to its water and air permeable weave, so heavy rain will pass through.

Frequently Asked Questions

Is this sail waterproof?
The fabric is water and air permeable, so it is not fully waterproof; it sheds some moisture but allows water through rather than acting as a solid rain barrier.

How should I measure for a custom sail?
Provide precise D-ring to D-ring measurements; leave at least 0.5 ft clearance between D-Rings and poles or reduce this spacing by 1 to 1.5 ft per side if needed for installation geometry.

Will it hold up in wind?
Customers report strong performance in high winds when installed correctly, and the reinforced edges with stainless D-Rings are designed for commercial-standard durability.
