ColourTree Custom Size 11ft x 13ft x 17ft Sand Beige Right Triangle

In this review of the ColourTree custom size shade sail, the verdict is practical: this heavy duty right triangle shade is best for homeowners and light commercial users who want a breathable, high-UV protection canopy that resists fading. It stands out because it uses 190 GSM 100% virgin HDPE treated with a UV stabilized compound, which the maker reports passed extended laboratory UV testing; that combination is the single biggest reason to choose it for long seasons of sun exposure. The reviewer found it straightforward to handle, provides strong shade, and pairs well with proper installation hardware.

Key Features

• 190 GSM Virgin HDPE: Thick, non-recycled material gives a sturdy feel and is intended to last longer under sun exposure than recycled alternatives.
• UV Stabilized Compound: Fabric treated to resist drying, tearing and fading, which helps extend useful life in sunny climates.
• 95% UV Blockage: High UV rejection significantly reduces direct sunlight and heat in the shaded area, improving comfort around pools or patios.
• Breathable Woven Fabric: Allows air and water to pass through so rain does not pool and the covered area stays cooler and ventilated.
• Reinforced Edges and Stainless D-rings: Double layered stitched seams and heavy stitching at corners keep the sail shaped and make attachment points more secure.
• Three Year Warranty: Limited warranty under normal use provides buyer reassurance for season-to-season use.

Who It's For

This shade sail is aimed at homeowners, pool owners and small commercial sites that need reliable sun screening and prefer a heavier, UV-tested fabric. It works well for patios, carports, balconies and above-ground pools where a right triangle layout fits the space.

It is less suitable for installations where users expect to rely on included mounting hardware (hardware is sold separately) or need ultra-lightweight sails for temporary events. If absolute worry-free longevity under extreme weather is required, consider a more robust fixed structure rather than a fabric sail.

Pros & Cons

Pros

• High quality 190 GSM virgin HDPE gives a solid, durable feel and improved UV resistance.

• Three year limited warranty provides reasonable protection under normal use.

Cons

• Installation hardware is sold separately and must be chosen carefully; using weak ropes can cause failure.
