Custom Size 17ft x 20ft x 26.2ft Green Right Triangle Sun Shade Sail

Our review of this custom right triangle shade sail finds it best for homeowners and small commercial spaces that need wide, reliable sun protection without a rigid canopy. The single biggest reason to consider it is its strong sun-blocking fabric: crafted from 200 GSM HDPE, the sail claims up to 95% UV blockage and noticeably lowers ambient temperature under the shade. Installation requires some planning but the flexible mounting options make it adaptable to trees, poles, roofs or walls.

Key Features

• 95% Sun Protection: The 200 GSM HDPE material blocks up to 95% of UV rays to reduce sun exposure for people and outdoor furnishings.
• Temperature Reduction: The ventilated, woven fabric can lower the shaded area by as much as 15 degrees compared with unshaded spots.
• Custom Fit: Made to measure from D-ring to D-ring so the sail can be tailored to irregular or specific spaces for a neater installation.
• Durable Construction: Reinforced edges, stainless steel D-rings and double-layer stitching improve longevity for frequent outdoor use.
• Flexible Installation: Can be attached to trees, roofs, walls or poles and works with standard mounting hardware kits for varied site conditions.
• Water & Air Permeable: The breathable weave sheds heat while allowing airflow and some water passage, reducing wind load on the fabric.

Who It's For

This shade sail is aimed at homeowners, cafes, playgrounds or poolside areas that need a large, shaped canopy and want strong UV protection without a permanent structure. The customizable sizing is especially useful for odd-shaped spaces or where precise D-ring to D-ring dimensions are required.

Those who need a fully waterproof awning, or who expect continuous heavy rain coverage, should look elsewhere because the fabric is water-permeable rather than watertight. Also, buyers seeking a kit with rigid poles included should check hardware compatibility before ordering.

Pros & Cons

Pros

• Excellent sun protection from the 200 GSM HDPE fabric that blocks most UV rays.
• Reduces temperature under the sail, making outdoor areas more comfortable in hot weather.
• Durable details such as stainless steel D-rings and double-layer stitching add robustness.
• Custom sizing allows a tailored fit for awkward or large spaces.

Cons

• Some customers report mixed long-term durability in very harsh sun; lifespan can vary by exposure.
• Not fully waterproof, so it does not replace a sealed canopy for heavy rain protection.

Specifications

Our Verdict

This custom right triangle shade sail is a practical, cost-effective option for anyone needing robust sun protection and a cooler outdoor area. It is good value when ordered to fit a specific space and benefits from durable hardware and reinforced stitching, though buyers should account for site exposure and that it is water-permeable rather than waterproof.

Frequently Asked Questions

Is this sail waterproof?
Answer. The fabric is water and air permeable, so it sheds some water but is not fully waterproof for heavy rain.

How should I measure for a custom sail?
Answer. Measure from D-ring to D-ring and leave at least 0.5 ft gap between D-rings and poles or reduce by 1 to 1.5 ft per side as recommended for optimal tension.

What hardware is included?
Answer. The product features stainless steel D-rings and reinforced edges; mounting hardware kits are referenced for installation but check whether a pole kit is needed separately.
