11 ft x 17 ft x 20.2 ft Black Right Triangle Sun Shade Sail - Heavy

In this review the ColourTree right triangle sun shade sail is assessed for homeowners and small commercial spaces that need reliable UV protection and durable fabric. The bottom line: this shade sail is best for people who want a heavy duty, breathable canopy that blocks most UV while resisting fading and tearing; it excels where long-term sun exposure is a concern. The reviewer found the build quality, material thickness and UV stabilization to be the single biggest reason to buy for patios, pools and carports.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric offers a sturdy feel and resists tearing under regular outdoor use, giving confidence in long term performance.
• UV stabilized compound: Material treated to resist drying and fading after extended sun exposure, which helps the canopy keep its color and strength.
• 95% UV blockage: Effective reduction of harmful UV and noticeable temperature drop in shaded areas, making it useful for patios and poolside shade.
• Breathable woven fabric: Allows air and water to pass so rain does not pool and the shaded space stays ventilated and cooler.
• Reinforced seams and stainless D-rings: Double layered stitched edges and heavy stitching at corners improve durability and make mounting more secure.
• 3 year limited warranty: Warranty coverage under normal weather and usage gives added assurance for longer term ownership.

Who It's For

This shade sail suits homeowners, landscapers and small commercial operators who need a robust sun shelter for patios, balconies, swimming pools or carports and who value UV protection and fabric longevity. Its heavy duty 190 GSM virgin material and reinforced construction make it a good choice where constant sun and occasional wind exposure are expected.

It is less appropriate for buyers who need a lightweight temporary cover for short events or those who require a full waterproof canopy; the woven, breathable fabric is designed to let water through rather than pool or shed it as a solid tarp would.

Pros & Cons

Pros

• High quality 190 GSM virgin HDPE offers superior durability and resistance to sun damage.
• Blocks about 95% of UV, noticeably reducing heat and sun exposure underneath.
• Breathable weave prevents water pooling and improves airflow in shaded areas.
• Sturdy construction with reinforced seams and stainless steel D-rings for long-term attachment.

Cons

• Installation requires additional hardware kits and proper cables, which are sold separately.
• Not fully waterproof because the fabric is breathable, so it will let rain pass through.
