ColourTree Custom Size 9ft x 9ft x 12.7ft Right Triangle Sun Shade

Our review of the ColourTree 9' x 9' x 12.7' right triangle sun shade sail finds it best suited to homeowners and small commercial spaces that need a durable, high-UV block canopy. The single biggest reason to consider this shade is its 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which the manufacturer says was lab tested for long-term sun exposure. It delivers strong sun protection and breathability, making it a practical covering for patios, pools and carports while avoiding water pooling on rainy days.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled material offers increased durability under sun exposure compared with recycled alternatives.
• UV stabilized compound: Fabric treatment reduces drying, tearing and fading for an extended service life in outdoor conditions.
• 95% UV blockage: Blocks most harmful UV rays and noticeably reduces heat in shaded areas for more comfortable outdoor use.
• Breathable woven fabric: Allows air and water to pass through so rain does not pool and ventilation is maintained under the canopy.
• Reinforced edges and stainless D-rings: Double layered stitched seams and heavy stitching at corners improve load distribution and attachment strength.

Who It's For

This shade sail is aimed at homeowners, pool owners and small businesses that want a straightforward, heavy duty canopy that prioritizes UV protection and longevity. It works well where an angled right triangle layout fits the available mounting points, such as above a patio, above-ground pool or carport.

People who need a custom-shaped engineered structure, a full waterproof canopy, or those who cannot access secure anchor points should look elsewhere; hardware kits are required but sold separately, and installation depends on suitable poles, walls or trees and good tensioning to avoid stress on the fabric.

Pros & Cons

Pros

• Durable 190 GSM virgin HDPE material offers improved resistance to sun damage compared with recycled fabric.

• Well reinforced seams and stainless steel D-rings make attachment straightforward and robust when proper hardware is used.

Cons

• Size and fit require careful measuring and some customers reported mismatch issues or tearing if not properly installed or tensioned.
• Installation hardware is not included and must be purchased separately, adding to total cost and setup time.
