ColourTree Custom Size 21ft x 21ft x 29.7ft Right Triangle Sun Shade

In this review the ColourTree right triangle sun shade sail is assessed for homeowners and small commercial spaces seeking durable, high UV protection coverage. The bottom line: this sail is best for people who want a heavy duty, long-lasting fabric that blocks heat and sun without trapping water. Our review finds the fabric quality and reinforced construction the single biggest reasons to consider it, particularly where continuous sun exposure and reliable shade are priorities.

Key Features

• 190 GSM Virgin HDPE: The thick 190 GSM 100% virgin woven fabric provides a sturdy feel and is designed to resist tearing and premature wear compared with recycled materials.
• UV Stabilized Compound: Laboratory UV testing to 20000 hours and UV stabilization help prevent fading and drying, extending the useful life under strong sunlight.
• 95% UV Blockage: The weave blocks up to 95% of harmful UV, noticeably reducing sunlight and heat in shaded areas like patios and pools.
• Breathable, Water-Permeable Weave: The fabric lets air and water pass through, preventing water pooling after rain and improving cooling under the sail.
• Reinforced Edges and Stainless D-Rings: Double layered stitched seams and heavy stitching at corners with stainless steel D-rings provide secure anchoring and resistance to frayed edges.
• Three Year Limited Warranty: A 3 year limited warranty covers normal weather and usage, offering extra peace of mind for long term installations.

Who It's For

The ColourTree right triangle sail is ideal for homeowners, cafes, and small businesses that need broad shade coverage over patios, pools, carports, or balconies and that want a product made from thicker, virgin HDPE for better durability. It suits installations where wind and sun exposure are frequent, and where breathable fabric is preferred to avoid wet weather pooling.

It is less suitable for buyers who require a full hardware kit with the sail; installation hardware and cable are sold separately, and users should plan for proper hardware or professional installation rather than relying on simple ropes.
