ColourTree Custom Right Triangle Shade Sail 13ft x 17ft x 21.4ft

Our review of the ColourTree custom right triangle shade sail finds it best for homeowners and small commercial spaces that need a durable, high-coverage shelter from sun and heat. The single biggest reason to buy is its heavy 190 GSM virgin HDPE fabric treated with a UV stabilized compound, which customers report holds up well in prolonged sun exposure and preserves color and strength over seasons. Installation requires separate hardware kits, but once mounted the sail provides reliable 95% UV blockage and breathable shade for patios, pools, balconies, and carports.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric gives a sturdier weave that resists tearing and stretches less under load than recycled options.
• UV stabilized compound: Treated material resists drying out and fading after extended sun exposure, extending usable life in hot climates.
• 95% UV blockage: The dense weave significantly reduces UV sunlight and lowers temperature in shaded areas for more comfortable outdoor use.
• Breathable woven fabric: Allows water and air to pass through so rain does not pool on the sail and ventilation reduces heat buildup underneath.
• Reinforced edges and D-rings: Double layered stitched seams and stainless steel D-rings with heavy stitching make mounting points stronger and reduce fraying.
• 3 year limited warranty: Manufacturer warranty covers normal weather and usage, providing added confidence for longer term installations.

Who It's For

This shade sail is a strong fit for homeowners with patios, decks, or pools who need large, angled coverage and prefer a heavy-duty, long-lasting fabric that resists sun damage. It also suits small businesses or cafes that want an attractive, functional shade solution without frequent replacements.

Shoppers who need a complete hardware kit should look elsewhere or plan to purchase mounting cables and fittings separately, and those wanting an exact pre-drilled mounting system integrated into a kit may prefer a different package. For very small balcony installations the size may be larger than needed.
