Right Triangle Sun Shade Sail Canopy 17ft x 21ft x 27ft Turquoise

In this review the ColourTree right triangle sun shade sail is presented for homeowners and small commercial sites who need large, reliable UV protection. The bottom line: this 17' x 21' x 27' turquoise canopy is built from thick 190 GSM virgin HDPE and is designed to block up to 95% of UV while remaining breathable, making it a strong option for patios, pools, and carports where durability under sun exposure matters most.

Key Features

• 190 GSM Virgin HDPE: The heavy material provides a thicker, more durable fabric that resists tearing and extends service life compared with recycled alternatives.
• UV Stabilized Compound: Fabric treated for UV stability after 20,000 hours of lab testing helps prevent drying out and fading in strong sunlight.
• 95% UV Blockage: The woven fabric significantly reduces UV sunlight and lowers temperature in shaded areas, improving comfort for outdoor living.
• Breathable and Water-Permeable: The weave lets air and water pass through so rain does not pool on the canopy and ventilation remains good beneath the sail.
• Reinforced Construction: Double layered stitched seams and stainless steel D-rings at each corner provide secure attachment points and reduce edge fraying.
• 3 Year Limited Warranty: The product is backed by a limited warranty under normal weather and use for buyer assurance.

Who It's For

The sail is well suited to homeowners, pool owners, and light commercial settings that need broad, effective shade and a fabric that will stand up to long sun exposure - for example patios, balconies, carports, and outdoor seating areas in sunny climates. Installers who want a heavy-duty fabric and neat, finished edges will appreciate the reinforced seams and stainless steel D-rings.

Those who should look elsewhere include buyers who need an all-weather waterproof canopy (this product is water-permeable by design) or anyone unwilling to purchase separate installation hardware, since cables and mounting kits are required and sold separately for proper tensioning.
