ColourTree CTAPR1220 17ft x 21ft Sand Beige Sun Shade Sail - Heavy

In this review of the ColourTree 17' x 21' Sand Beige sun shade sail, the bottom line is simple: this heavy duty rectangle is for homeowners and businesses that want durable UV protection without trapping heat. The reviewer found the sail's standout advantage is its 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which is designed to resist fading and tearing and to block 95% of harmful UV. Installation needs basic hardware sold separately, but the fabric and construction make it an attractive choice for patios, pools and carports.

Key Features

• 190 GSM virgin HDPE: Thicker, non-recycled fabric offers stronger resistance to sun exposure and claims greater long-term durability compared with recycled options.
• UV stabilized compound: The material is treated to reduce drying, tearing and color fade so the sail keeps its appearance longer in strong sunlight.
• 95% UV blockage: The woven fabric significantly reduces UV sunlight and lowers temperature in the shaded area for more comfortable outdoor use.
• Breathable woven design: Allows air and water to pass through to prevent pooling and to keep the shaded area ventilated during warm weather.
• Reinforced edges and D-rings: Double layered stitched seams and stainless steel D-rings create stronger anchor points and reduce fraying at the corners.
• Commercial standard build: Heavy duty construction intended for repeated outdoor use and backed by a 3 year limited warranty under normal conditions.

Who It's For

This shade sail suits homeowners with patios, balconies, pools or carports who need reliable sun protection and prefer a breathable cover that does not trap heat. It is also a fit for small commercial applications where a rectangular shade footprint and robust material are priorities.

People who want a full mounting kit in the box should look elsewhere, since installation hardware and cables are sold separately and the manufacturer recommends stainless or steel cable hardware rather than nylon rope. Those expecting an ultra-light or decorative fabric rather than a heavy duty commercial weave may also prefer a different product.

Pros & Cons

Pros

• High density 190 GSM virgin HDPE fabric feels noticeably thicker and resists sun damage better than typical recycled fabrics.
• Blocks about 95% of UV and improves comfort by reducing direct sunlight and heat in covered zones.
• Breathable woven structure prevents water pooling and helps keep the covered area ventilated.
• Reinforced stitched edges and stainless steel D-rings provide sturdy anchor points for installation.

Cons

• Installation hardware is not included and poor quality ropes can fail, so buyers must plan for compatible fittings and cable kits.
• Customer reports on durability are mixed in extreme conditions, so very high-wind locations may need extra reinforcement or a different mounting strategy.
