11ft x 14ft x 17.8ft Gray Right Triangle Sun Shade Sail - UPF50

Our review of the 11' x 14' x 17.8' gray right triangle sun shade sail finds it best suited to homeowners and small commercial spaces that need reliable sun protection with a custom fit. The biggest reason to consider this shade sail is its combination of high UV blockage and practical construction: made from 200 GSM HDPE it blocks up to 95% of UV and reduces temperature under the sail, so it genuinely improves outdoor comfort while remaining breathable and water permeable.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful rays for safer outdoor time.
• Temperature reduction: The sail can lower air temperatures beneath it by as much as 15 degrees compared to unshaded areas, making patios more usable on hot days.
• Custom sizing: Measurements are taken D-ring to D-ring so the sail can be ordered to fit irregular or specific spaces instead of relying on one-size options.
• Durable construction: Reinforced edges, stainless steel D-rings and double-layer stitching reduce fraying and extend service life.
• Breathable and water permeable: The HDPE weave allows air and water to pass, preventing heat-trapping and puddling after light rain.
• Flexible installation: Can be attached to trees, roofs, walls or poles with standard mounting hardware and simple spacing guidance for best tension.

Who It's For

This shade sail suits homeowners, cafes, and small commercial patios that need a tailored triangular shade and want strong sun protection without blocking airflow. It is a good choice when a specific D-ring to D-ring measurement is required to cover an odd-shaped area or when a cooler shaded spot is desired for seating or play.

Those who need a permanent waterproof canopy, a rigid structure, or want a warranty-backed marine-grade fabric should look elsewhere; the product is designed as a breathable, UV-blocking sail rather than a fully waterproof awning and customer reports show mixed long-term durability in very harsh sun exposure.

Pros & Cons

Pros

• High rated UV blockage with a tangible drop in temperature under the sail.
• Custom sizing from D-ring to D-ring for a tailored fit to awkward spaces.
• Stainless steel D-rings and reinforced stitching for improved durability and secure mounting.
• Breathable design avoids heat trapping and allows rain to pass through.

Cons

• Durability is mixed in long-term sun exposure, with some users reporting degradation after a year or so.
• Not fully waterproof, so it will not replace a sealed awning in heavy rain.

Our Verdict

Frequently Asked Questions

Is the sail waterproof?
The fabric is water permeable so it allows light rain to pass through rather than act as a waterproof tarp.

How are sizes measured?
Sizes are measured from D-ring to D-ring, and the seller offers customization or straight-edge options on request.

How long will it last in sun?
Many users report strong performance for over a year, but durability can vary with exposure; the product includes a 3-year assurance and uses reinforced stitching and stainless D-rings.
