ColourTree Custom Size 4 ft x 17 ft Rainbow Waterproof Shade Sail

In this review the ColourTree Custom Size 4 ft x 17 ft Rainbow shade sail is evaluated for homeowners and small outdoor-space users who want a durable, waterproof sun cover that also blocks UV. The bottom line: this is a straightforward choice for patios, carports and play areas because the 220 GSM pure polyethylene fabric combined with a waterproof coating and reinforced stitching delivers dependable protection and useful longevity. The review focuses on build quality, water resistance, and practical installation details observed by users.

Key Features

• Durable material: The 220 GSM pure virgin polyethylene fabric feels thick and substantial, so it resists wear and retains shape under tension.
• Waterproof coating: A sealed waterproof layer prevents water penetration, letting the sail serve as both sun shade and rain shelter.
• UV protection: Finished with commercial grade UV resistant treatment to maintain color and block up to 95% of UV rays.
• Reinforced edges: Double reinforced stitched seams reduce the risk of tearing where the sail is under load, which helps the D-rings stay secure.
• Premium fittings: Each corner has a 316 stainless steel D-ring for corrosion resistance and easier, long-term mounting.
• Warranty: A 3 year limited warranty offers free replacement if the product does not meet expectations, which adds peace of mind.

Who It's For

This shade sail is best for homeowners with patios, small carports, decks or yard play areas who need a custom-sized cover that is both sun-blocking and water resistant. It works particularly well where a compact, colorful canopy is wanted and where corrosion-resistant hardware matters.

It is less appropriate for those who need an ultralight temporary cover or a fully rigid structure; heavy, fixed awnings or greenhouse-grade roofing are outside its intended use. Also, people seeking motor-vehicle garage-level protection from prolonged heavy storms should consider a dedicated carport structure instead.

Pros & Cons

Pros

• High build quality thanks to 220 GSM pure polyethylene and reinforced seams for long service life.
• Reliable water resistance keeps areas dry under moderate rain and prevents water seeping through.
• 316 stainless steel D-rings and UV treatment help resist rust and fading for outdoor use.
• Three year limited warranty provides added confidence and a replacement option if needed.

Cons

• The sail requires proper tensioned mounting and suitable anchor points to perform well; installation may need extra hardware for some locations.
• As a fabric canopy it will not replace a rigid roof for heavy, prolonged weather exposure.

Specifications

Our Verdict
