10 ft x 17 ft x 19.7 ft Blue Right Triangle Sun Shade Sail - UPF50

Our review of this custom-size right triangle shade sail finds it best for homeowners and small businesses who need large, tailored sun protection without a rigid canopy. The biggest reason to consider it is the 95% sun protection from 200 GSM HDPE fabric, which noticeably cools shaded areas and blocks most harmful UV rays. Installation is straightforward for anyone comfortable with basic mounting hardware, and the option to order exact D-ring to D-ring measurements makes it a practical choice when standard sails do not fit the space.

Key Features

• 95% UV blockage: The 200 GSM HDPE fabric blocks up to 95% of UV rays for safer outdoor use and reduced sun exposure.
• Temperature reduction: The sail can lower ambient temperatures by up to 15 degrees compared with unshaded spots, improving comfort on hot days.
• Custom sizing: Measured and made from D-ring to D-ring, the sail can be tailored to fit irregular corners and nonstandard layouts.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings increase longevity and resist tearing under tension.
• Flexible installation: Can be attached to trees, roofs, walls or poles using standard mounting kits and allows spacing adjustments for tension.
• Commercial standard: Built to a commercial-grade specification with a 3-year assurance included for added confidence.

Who It's For

This shade sail is ideal for homeowners with patios, playgrounds or poolside areas who want a clean, permanent-looking shade solution that can be tailored to an odd-shaped space. Small businesses such as cafes or daycare centers that need a simple, breathable canopy to protect customers or children from sun exposure will also benefit.

It is less suitable for buyers who need a fully waterproof or solid rainproof awning, since the fabric is water and air permeable and designed primarily for sun protection. Also, those seeking a lifetime, maintenance-free product should note that long-term durability can vary with exposure and care.

Frequently Asked Questions

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

How should I measure for a custom sail?
Measure from D-ring to D-ring at each corner and provide those dimensions so the sail is made to fit the mounting points precisely.

How long will it last outdoors?
Construction uses reinforced edges and stainless D-rings and comes with a 3-year assurance, but actual lifespan varies with sun exposure and local climate; some users report long service, others note degradation after extended intense sun.
