ColourTree Custom Size 15ft x 20ft x 25ft Blue Right Triangle Shade

In this review of the ColourTree custom size right triangle shade sail, the bottom line is simple: it is for anyone who wants sturdy, long-lasting sun protection for patios, pools or carports. The biggest reason to buy is the fabric - a 190 GSM 100% virgin HDPE that the maker says was UV tested for long-term durability, which translates into effective sun blocking and color stability in strong sun. Installers should plan for proper hardware and ropes, but once mounted it provides reliable shade and breathability.

Key Features

• 190 GSM virgin HDPE: Thick non-recycled fabric gives the sail rigidity and resistance to tearing compared to thinner recycled alternatives.
• UV stabilized compound: The fabric is treated to resist drying out and fading after prolonged sun exposure, extending usable life in outdoor settings.
• Blocks 95% UV: High UV blockage reduces direct sunlight and helps lower temperatures in shaded areas for patios, balconies and pools.
• Breathable woven structure: The mesh lets air and water pass through to prevent pooling while maintaining sun protection.
• Reinforced edges and D-rings: Double-layer stitched seams and stainless steel D-rings provide durable anchor points for mounting.
• 3 year limited warranty: Warranty coverage gives some assurance of expected durability under normal use.

Who It's For

This shade sail is best for homeowners and small commercial users who need a reliable, large right triangle canopy to create permanent or semi-permanent shade over patios, swimming pools, play areas or carports. Its heavy 190 GSM virgin material is aimed at people who prioritize long-term UV resistance and color retention.

It is less suited to buyers who want a complete mounting kit included or who expect a lightweight, temporary tarp; hardware and proper stainless cables or kit must be purchased separately and fitted correctly for best performance.
