ColourTree Custom Size 21ft x 22ft x 30.4ft Beige Right Triangle Sun

In this review the ColourTree custom size right triangle sun shade sail is examined for homeowners and businesses who need large, durable UV protection. The bottom line: it is a robust, commercial-grade shade sail best for patios, pools and carports where long-term sun exposure is a concern. The reviewer finds the single biggest reason to buy is the heavy 190 GSM virgin HDPE fabric treated with UV stabilized compound, which delivers reliable UV blockage and durability in demanding outdoor conditions.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric provides a heavier, more tear-resistant canopy compared with recycled alternatives.
• UV stabilized compound: Factory UV treatment reduces drying, fading and tearing so the sail retains strength after prolonged sun exposure.
• 95% UV blockage: The woven mesh blocks most harmful UV and noticeably reduces temperature in shaded areas around patios and pools.
• Breathable, water-permeable weave: The fabric allows air and water to pass through so rain does not pool and the canopy stays cooler and maintenance-free.
• Reinforced edges and stainless D-rings: Double-layer stitched seams and heavy stitching at corners keep the sail true to shape and make installations secure when paired with proper hardware.
• Commercial warranty: A 3 year limited warranty gives added confidence under normal weather and use conditions.

Who It's For

This shade sail is aimed at homeowners, property managers and small businesses who need a large, tailored shade solution for patios, swimming pools, balconies or carports and value long-term UV protection. It works particularly well where a true 90 degree corner or anchored triangle fit is required and where a heavy-duty fabric will resist sun and wind better than lighter alternatives.

Those who should look elsewhere include buyers seeking an off-the-shelf small sunshade under 10 ft, customers who want included installation hardware, or users who prefer a fully waterproof solid canopy; this product is a breathable mesh and requires separately purchased mounting hardware and cables for best results.

Pros & Cons

Pros

• High durability from 190 GSM 100% virgin HDPE for extended outdoor life.
• Effective sun protection with claimed 95% UV blockage to lower temperatures.
• Thoughtful construction with double-stitched seams and stainless D-rings for secure anchoring.
• Breathable weave prevents water pooling and reduces wind loading compared with solid fabrics.

Cons

• Installation hardware is sold separately, so buyers must purchase suitable cables and fittings to complete mounting.
• The mesh is not fully waterproof, so it will not provide complete rain protection like a solid canopy.
