ColourTree Custom Size 20ft x 21ft x 29ft Blue Right Triangle Sun

Our review of the ColourTree custom size right triangle sun shade sail finds it best suited for homeowners and small commercial spaces that need heavy duty, long-lasting sun protection in a bold color. The single biggest reason to buy is the 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which the reviewer found to resist fading and remain sturdy under prolonged sun exposure while blocking a large share of damaging UV. Installation requires separate hardware, but once mounted the sail cuts heat and glare noticeably.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric provides a robust feel and resists tearing better than lighter recycled sails.
• UV stabilized compound: The fabric is treated to reduce drying, fading and brittleness after extended sun exposure, extending usable life.
• 95% UV blockage: The sail significantly lowers sunlight and UV in the shaded area, making patios, pools and balconies more comfortable.
• Breathable woven material: Air and rain pass through the mesh to prevent water pooling while still offering substantial shade and cooling.
• Reinforced edges and D-rings: Double-layer stitched seams and stainless steel D-rings improve durability and make attachment points more reliable.
• 3 year limited warranty: The warranty covers normal use and provides additional reassurance for long-term outdoor installation.

Who It's For

The sail is ideal for homeowners, restaurants or pool owners who want a durable, commercial-grade shade solution with a striking blue color and custom sizing for a corner or nonstandard span. It suits anyone who values UV protection and durability over ultra-lightweight, temporary covers.

Those who should look elsewhere include buyers who need a complete mounting kit included or people who prefer a fully waterproof canopy; this product requires separate hardware and is a breathable mesh rather than an impermeable fabric.

Pros & Cons

Pros

• High-quality 190 GSM virgin material offers improved durability and resistance to sun damage.
• Blocks up to 95% of UV while remaining breathable so rain drains through instead of pooling.

• Good value for long-term outdoor shade with a 3 year limited warranty.

Cons

• Installation hardware is sold separately, adding extra cost and planning for proper attachment.
• As a breathable mesh it does not provide full waterproofing for heavy, driving rain.
