ColourTree CTAPRT10 Custom 21ft x 21ft x 21ft Blue Triangle Sun Shade

In this review of the ColourTree CTAPRT10 custom triangle sun shade sail, the bottom line is simple: it is for anyone who needs a durable, high-coverage outdoor shade that resists fading and blocks the sun. The reviewer found the sail most valuable for patios, poolsides and carports where long-term UV protection and airflow matter. The single biggest reason to buy is the thick 190 GSM virgin HDPE fabric treated with UV stabilized compound, which the manufacturer says was lab-tested to resist sun damage and extend lifespan.

Key Features

• 190 GSM Virgin HDPE: The thick, non-recycled fabric feels robust and is designed to resist tearing and degradation under heavy sun exposure.
• UV Stabilized Compound: Treated material is made to resist drying out and fading so the sail keeps color and strength over time.
• 95% UV Blockage: The woven mesh blocks the majority of harmful UV, lowering direct sunlight and cooling shaded areas.
• Breathable Woven Fabric: Air and water pass through the mesh to avoid pooling and make the sail suitable in light rain without sagging.
• Reinforced Seams and D-rings: Double layered stitched edges and stainless steel D-rings improve durability and make mounting points secure.
• Three Year Warranty: A limited 3 year warranty provides reasonable assurance for normal weather and usage.

Who It's For

Homeowners with a need for large, permanent-looking shade over patios, spas, pools or carports will appreciate this sail. The thick 190 GSM fabric and reinforced corners suit locations with strong sun exposure where long-term UV resistance and color retention are priorities.

It is less suitable for buyers who need a temporary or very lightweight shade or those who expect a fully waterproof canopy; the mesh is breathable by design and allows water through. Also note that installation hardware is not included, so customers without mounting anchors should budget for a compatible hardware kit.

Pros & Cons

Pros

• High-quality 190 GSM virgin HDPE fabric provides substantial durability and sun resistance.
• Blocks approximately 95% of harmful UV while remaining breathable to prevent water pooling.
• Well-constructed edges with heavy stitching and stainless steel D-rings for secure attachment.

Cons

• Installation hardware is sold separately, so additional purchase and planning are required.
• The mesh design allows water through, so it will not provide full rain protection like a solid canopy.
