ColourTree 11ft x 18ft x 21.1ft Turquoise Triangle Shade Sail

In this review of the ColourTree custom size turquoise triangle shade sail, the bottom line is simple: this is a practical, heavy-duty canopy for anyone who needs reliable sun and rain protection for patios, gardens, or carports. The sail's standout feature is its waterproof coated 220 GSM 100% virgin polyethylene fabric with commercial UV stabilization, which delivers strong UV blockage and keeps rain from soaking through. The construction and hardware aim to make installation and long-term use straightforward for DIYers and homeowners who want an attractive, functional cover.

Key Features

• Waterproof coating: The finish prevents water from passing through so the sail functions as both sun shade and rain shelter for outdoor spaces.
• 220 GSM virgin polyethylene: A dense, non-recycled fabric that improves durability and resists thinning from sun exposure.
• Commercial UV stabilization: Factory UV treatment delivers up to 95% UV blockage to protect people and furniture beneath it.
• 316 stainless steel D-rings: A premium grade D-ring on each corner makes hanging and tensioning the sail easier and more secure.
• Double reinforced stitching: Heavy stitched seams increase tear resistance and strengthen the anchor points under load.
• Three year limited warranty: The warranty offers free replacement if the product is unsatisfactory during the limited period, adding purchase confidence.

Who It's For

The ColourTree triangle shade sail is best for homeowners, gardeners, and renters who need an affordable custom-size shade and shelter solution for a patio, carport, or yard. It suits people who want a visible, decorative piece that still performs - customers report it looks great while blocking sun and surviving wind gusts.

People who need an ultra-lightweight temporary sunsheet or who require full enclosure and structural framing should look elsewhere; this product is designed as a stretched sail using attachment points rather than a rigid canopy. Also, those requiring specific color-matching beyond standard turquoise should confirm options before ordering.

Pros & Cons

Pros

• High material quality and dense 220 GSM fabric that customers praise for durability and feeling substantial.

• Attractive appearance that adds whimsy to outdoor spaces while still allowing natural light through.
• Solid hardware and stitching, including 316 stainless steel D-rings and double reinforced seams, for long-term tensioned use.

Cons

• As a stretched sail, it requires secure anchor points and correct tensioning; installation is not fully hands-off for all users.
• Custom sizing means you should measure carefully before ordering to ensure a proper fit for your space.
