ColourTree 11ft x 17ft x 20.2ft Triangle Waterproof Sun Shade Sail

In this review the ColourTree 11' x 17' x 20.2' triangle shade sail is examined for homeowners and gardeners who need a durable, waterproof canopy that also blocks UV. The bottom line: this sail is best for patios, carports, and yard areas where a robust, long-lasting fabric and secure attachment points matter most. The single biggest reason to buy is the combination of 220 GSM virgin polyethylene material with commercial UV stabilization and reinforced corners, which delivers both water resistance and lasting UV protection.

Key Features

• 220 GSM 100% virgin polyethylene: Provides a thick, non-recycled fabric base that resists tearing and retains shape under sun exposure.
• Commercial UV stabilization: Built-in UV treatment helps preserve color and strength while offering significant sun blockage for outdoor living areas.
• Waterproof coated surface: The coating keeps rain from passing through so the sail can function as a canopy alternative for patios and carports.
• 316 stainless steel D-rings: One premium grade D-ring at each corner makes hanging straightforward and improves corrosion resistance near humid or coastal locations.
• Double reinforced stitched seams: Heavier sewing and seam reinforcement increase pulling strength and reduce the chance of seam failure under load.
• 3 year limited warranty: Manufacturer covers free replacement if you are not satisfied within the warranty period, giving added peace of mind.

Who It's For

The ColourTree triangle sail is ideal for homeowners, gardeners, and small business owners who need reliable shade and occasional weather protection over a patio, garden bed, or parking spot. It suits people who want heavy-duty fabric rather than a lightweight mesh and who appreciate reinforced corners and stainless hardware for installation stability.

It is less suitable for those who need a permanent roof replacement or a seamless, rigid structure; a fixed gazebo or hardtop would be a better choice for continuous, heavy snow loads or fully enclosed shelter needs. Also, if a furnished living space needs complete sun blackout, a thicker permanent canopy may work better.

Pros & Cons

Pros

• High-quality 220 GSM virgin polyethylene feels substantial and resists wear over seasons.
• Waterproof coating effectively sheds rain and can hold off water in heavy showers, according to user reports.
• Stainless steel 316 D-rings and double-stitched seams increase durability and ease installation.
• Three year limited warranty offers a straightforward replacement option if expectations are not met.

Cons

• As a fabric sail it is not a permanent rigid structure and can collect water if not tensioned or angled correctly.
• Color tones may vary slightly in sunlight over time despite stabilization, depending on placement and exposure.
