ColourTree 17 ft x 20 ft Red Sun Shade Sail Canopy - Heavy Duty UV

Our review of the ColourTree 17' x 20' red sun shade sail finds it best suited for homeowners and small businesses who want a durable, breathable canopy that blocks most UV without a permanent structure. The clearest reason to buy is the fabric: this shade sail uses 190 GSM 100% virgin HDPE treated with a UV stabilized compound that the manufacturer says survived extended laboratory UV testing, and that construction translates into a noticeably sturdy, fade-resistant panel that still lets air and water pass through. Installation is straightforward for someone comfortable fitting anchors and cable, and the finished look is neat and effective at cooling patios and poolside seating.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric provides a heavier, more durable canopy that resists tearing and drying out under prolonged sun exposure.
• UV stabilized compound: Special treatment helps prevent fading and material breakdown so the canopy keeps its color and strength longer than untreated woven sails.
• 95% UV blockage: The woven material significantly reduces harmful UV and lowers ambient temperature in shaded areas for more comfortable outdoor time.
• Breathable weave: The fabric allows air and water to pass through, preventing pooling and reducing wind load while maintaining shade performance.
• Reinforced edges and D-rings: Double layered stitched seams and stainless steel D-rings deliver secure attachment points and reduce fraying at anchor zones.
• Three year limited warranty: The included warranty gives reasonable coverage under normal use and offers added confidence in build quality.

Who It's For

The ColourTree shade sail is ideal for homeowners with patios, balconies, carports or poolside seating who want an affordable, semi-permanent solution to afternoon sun and UV exposure. It also fits small commercial settings such as cafe terraces or playgrounds where breathability and UV protection matter.

It is less well suited for locations needing a rigid, waterproof roof or people who cannot install proper hardware; the sail requires separate high-quality cable and mounting kits and is designed to let water through, not to keep rain out.

Pros & Cons

Pros

• Durable virgin 190 GSM fabric resists fading and tearing for long-term outdoor use.
• Blocks about 95% of UV while remaining breathable, which cools shaded areas effectively.
• Reinforced seams and stainless steel D-rings make mounting secure and reduce edge wear.
• Good value for those wanting a cheaper alternative to building a permanent shade structure.

Cons

• Not waterproof-breathable fabric allows water through, so it will not shelter from heavy rain.
• Hardware kits are sold separately, so installation requires additional purchases and some DIY skill.
