Right Triangle 12ft x 12ft x 17ft White Sun Shade Sail - 190 GSM Mesh

In this review we look at the ColourTree right triangle sun shade sail and why it stands out for homeowners and small commercial spaces that need durable sun protection. The bottom line: this 12ft x 12ft x 17ft white sail uses a heavy 190 GSM virgin HDPE fabric treated with UV stabilized compound, which is the single biggest reason to buy it if longevity and serious UV blockage matter. Our review found it provides strong, breathable shade while resisting fading and tearing under prolonged sun exposure.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric gives a robust feel and resists wear better than lighter recycled sails.
• UV stabilized compound: Factory treatment prevents drying, tearing and fading so the fabric keeps its shape and color longer outdoors.
• 95% UV blockage: The woven mesh significantly reduces sunlight and heat in the covered area, improving comfort for patios and pools.
• Breathable woven design: Allows air and water to pass through to avoid pooling and reduce wind stress on the mounting points.
• Reinforced edges and stainless D-rings: Double layered stitched seams and heavy stitching at corners create a secure attachment point for cables and hardware.
• Three year limited warranty: Warranty coverage provides added confidence in normal weather and usage conditions.

Who It's For

This sail is best for homeowners, small businesses or property managers who need a durable, breathable shade solution for patios, balconies, pool sides or carports and who value long-term UV resistance. The right triangle shape is useful for fitting into corners, over decks, and in asymmetric spaces where a square or rectangle would not work.

Those who should look elsewhere are buyers who want a fully waterproof canopy or an exact custom mounting kit included; installation hardware is sold separately and the mesh fabric is designed to be breathable rather than watertight. If a lighter, temporary shade is required, a thinner recycled fabric might be a better low-cost option.

Pros & Cons

Pros

• High-quality 190 GSM virgin material feels substantial and resists sun damage.
• Blocks up to 95% of harmful UV to reduce heat and sun exposure under the sail.
• Breathable fabric prevents water pooling and reduces wind load on fittings.
• Reinforced seams and stainless steel D-rings make installation secure and durable.

Cons

• Hardware and cables are not included, so buyers must purchase recommended kits separately for best performance.
• Breathable mesh is not waterproof, so it will not provide complete rain protection.
