Custom Size 9ft x 15ft x 17.5ft Red Right Triangle Sun Shade Sail

In this review the reviewer looks at a Custom Size 9ft x 15ft x 17.5ft red right triangle sun shade sail intended for patios, driveways and backyard seating areas. The bottom line: this heavy-duty HDPE sail provides 95% sun protection and a noticeable temperature drop under the canopy, making it a practical choice for anyone who needs a larger, custom-fit shade that is easy to install and built for regular outdoor use.

Key Features

• ENHANCED 95% SUN PROTECTION: Blocks up to 95% of UV rays with 200 GSM HDPE fabric to reduce sun exposure for people and furnishings beneath the sail.
• TEMPERATURE REDUCTION: The weave and material can lower ambient temperature by up to 15 degrees compared to unshaded areas, making hot patios more comfortable.
• EASY & FLEXIBLE INSTALLATION: Can be attached to trees, roofs or poles using standard mounting kits and requires a gap of about 0.5 ft between D-rings and posts for best tension.
• CUSTOMIZABLE FIT: Sized by measuring D-ring to D-ring so the sail can be ordered to match irregular spaces and adjusted if straight edges are preferred.
• PREMIUM DURABILITY WITH 3 YEARS ASSURANCE: Reinforced edges, stainless steel D-rings and double-layer stitching add strength and include a 3-year assurance for peace of mind.

Who It's For

The shade sail is best for homeowners and small businesses that need a large, tailored shade solution for patios, play areas, or outdoor seating where sun protection and airflow are both important. Its custom measurement approach suits irregular areas and installations that use trees, posts or building anchors.

Those who want a rigid, waterproof canopy should look elsewhere, because this sail is water and air permeable and designed to reduce heat and block UV rather than create a dry, rainproof shelter. Installers should also be prepared to measure from D-ring to D-ring for an accurate fit.

Pros & Cons

Pros

• Very effective sun protection thanks to the 200 GSM HDPE fabric and advertised 95% UV blockage.
• Noticeable cooling effect, often reducing temperature under the sail by up to 15 degrees.
• Durable construction with stainless steel D-rings, reinforced edges and double-layer stitching for tougher outdoor use.
• Custom sizing makes it adaptable to odd-shaped spaces and specific installation points.

Cons

• While many users report good longevity, durability feedback is mixed and one report noted significant degradation after a little over a year in harsh sun.
• Not fully waterproof; it is air and water permeable so it will not keep rain out like a solid canopy.

Frequently Asked Questions

How should I measure for a custom fit?
Measure from D-ring to D-ring at the points where you plan to anchor the sail and provide those dimensions when ordering for the best fit.

Is the sail waterproof?
No, the fabric is water and air permeable so it reduces heat and sun but will not keep rain fully out like a solid tarp.

How durable is the material in sun exposure?
The 200 GSM HDPE and reinforced stitching offer good durability and a 3-year assurance, but user reports on long-term lifespan vary depending on sun intensity and local conditions.
