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

In this review of the custom size right triangle shade sail, the bottom line is simple: this product is for homeowners and commercial patios who need a durable, high-coverage sun screen that reduces heat and blocks the majority of UV. The reviewer found that the sail delivers on its main promise of sun protection and cooling, while also being flexible enough for varied mounting points. Installation takes some planning but the heavy-duty materials, reinforced edges and stainless steel D-Rings make this a practical choice for long-term outdoor shade.

Key Features

• 95% UV blockage: The fabric blocks up to 95% of harmful UV rays, providing safer outdoor time under strong sun.
• 200 GSM HDPE construction: The commercial-grade material resists fraying and holds shape under wind and sun exposure.
• Temperature reduction: The sail can lower ambient temperature by up to 15 degrees compared to unshaded areas, improving comfort.
• Reinforced hardware: Stainless steel D-Rings and double-layer stitching make the corners and edges more durable for repeated tensioning.
• Custom-fit sizing: Measured D-ring to D-ring, this made-to-order approach ensures a tailored fit for awkward or specific spaces.
• Breathable, water permeable: The weave sheds water while remaining air permeable so it does not trap heat or balloon excessively.

Who It's For

Homeowners with patios, decks or pool areas who want a substantial, long-lasting shade solution will benefit most from this custom right triangle sail; it is also a good option for small businesses that need a neat, high-coverage canopy for outdoor seating. The product suits anyone who prefers a fitted sail rather than a generic pre-cut size and values strong UV protection and reduced daytime temperatures.

Those who need a quick pop-up or temporary shelter should look elsewhere, as the sail requires planning for corner spacing and secure attachment points. If you cannot accommodate the recommended D-ring clearances or need an off-the-shelf size without customization, a different shade product may be more convenient.

Frequently Asked Questions

How should I measure for a custom sail?
Measure from D-ring to D-ring at the planned mounting points and follow the recommended corner gap guidelines to allow proper tensioning.

Is the sail waterproof?
The weave is water permeable rather than fully waterproof, so it sheds water but allows airflow to reduce ballooning and heat buildup.

How durable are the corners and hardware?
The product uses reinforced edges, double stitching and stainless steel D-Rings for improved durability under repeated tension and outdoor exposure.
