Right Triangle Sun Shade Sail Canopy 21ft x 23ft x 31.1ft Green

In this review the ColourTree right triangle sun shade sail is evaluated for homeowners and small commercial spaces seeking reliable UV protection without complex maintenance. The bottom line: this custom-size 21' x 23' x 31.1' green sail is best for those who need a heavy duty, breathable canopy that blocks sun effectively and lasts in harsh conditions. Our review finds the product stands out because of its thick 190 GSM virgin HDPE fabric treated with a UV stabilized compound, which delivers durability and strong sun blockage for patios, pools, carports and similar outdoor areas.

Key Features

• 190 GSM virgin HDPE: Thick non-recycled fabric provides a sturdy feel and resists tearing better than recycled alternatives under prolonged sun exposure.
• UV stabilized compound: Laboratory-tested to withstand extended UV exposure, helping prevent drying, fading and premature breakdown.
• 95% UV blockage: The woven mesh significantly reduces harmful UV and lowers temperature in shaded areas, improving comfort around pools and patios.
• Breathable woven fabric: Allows air and water to pass through so rain does not pool on the canopy and ventilation remains good beneath the shade.
• Reinforced edges and stainless steel D-rings: Double layered stitched seams and heavy stitching at corners keep the sail shaped and make mounting points durable.
• Custom made to order: The canopy is produced to the stated right triangle dimensions and typically requires 3-7 business days to make.

Who It's For

The sail is ideal for homeowners, small business owners and property managers who want a durable canopy with strong UV protection for patios, swimming pools, balconies and carports. People who value low maintenance will appreciate the breathable fabric that resists water pooling and reduces fading over time.

Those who need a quick off-the-shelf size or single-season temporary covers might look elsewhere, and buyers should plan to purchase proper shade sail hardware kits and galvanized cables separately for best results, since installation hardware is not included.

Pros & Cons

Pros

• Heavy 190 GSM virgin material that feels more robust and resists wear compared to recycled fabric options.
• High UV blockage and breathable weave that improves comfort without trapping rainwater.
• Reinforced seams and stainless steel D-rings for secure anchoring and long-term shape retention.
• Custom size production and a 3-year limited warranty provide confidence in durability.

Cons

• Installation hardware is sold separately, so additional cost and planning for cables and mounting kits is required.
• Custom production takes 3-7 business days, so it is not an immediate purchase for urgent needs.
