ColourTree Custom Size 13ft x 17ft x 21.4ft Brown Right Triangle Sun

In this review of the ColourTree Custom Size right triangle sun shade sail, the bottom line is simple: it is designed for people who need a heavy duty, UV-resistant canopy for patios, pools, or carports and want a tough, breathable fabric that reduces heat and sun exposure. The reviewer found the standout reason to buy is the 190 GSM virgin HDPE construction treated with UV stabilized compound, which promises greater durability and up to 95% UV blockage compared with typical recycled fabrics. Installation is straightforward if you use proper hardware, and the sail performs well at shading outdoor spaces.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric gives the sail a substantial feel and improved longevity under sun exposure.
• UV stabilized compound: Laboratory-tested material resists drying, tearing and fading so the sail keeps shape and color longer.
• 95% UV blockage: The woven fabric cuts most harmful UV and lowers temperature in shaded areas for patios, pools and balconies.
• Breathable woven design: Allows air and water to pass through so rain does not pool and the shaded area stays ventilated.
• Reinforced edges and D-rings: Double layered stitched seams and stainless steel D-rings provide secure attachment points for a stable installation.
• 3 year limited warranty: Coverage under normal weather and usage offers reasonable reassurance for outdoor use.

Who It's For

This sun shade sail is best for homeowners and small businesses who need a large, robust shade solution over patios, above-ground pools, carports or outdoor seating areas. It suits users who prioritize material quality and UV protection and who will install the sail with rated shade hardware and cable rather than simple nylon rope.

Those who should look elsewhere include buyers seeking an inexpensive, temporary sun cover or those who cannot secure several solid anchor points; some customers reported sizing or early tear issues, so if you need a light, low-cost option or rapid replacement service, consider different, easier-to-replace coverings.
