White Right Triangle 15ft x 21ft x 25.8ft Sun Shade Sail - Heavy Duty

In this review of the ColourTree custom-size right triangle sun shade sail, the bottom line is simple: anyone needing durable, high-coverage UV protection for a patio, pool area or carport will find this a strong option. The review focuses on how the 190 GSM virgin HDPE fabric performs in bright sun and how easy the triangle shape is to fit into tight outdoor spaces. It is especially compelling for buyers who want breathable shade that blocks sun without trapping heat or collecting rainwater.

Key Features

• 190 GSM Virgin HDPE: The thick, non-recycled material is designed to resist tearing and fading and to outlast recycled alternatives under intense sun exposure.
• UV Stabilized Compound: Laboratory-tested for long-term UV resistance, the fabric aims to stay flexible and avoid drying out over time.
• 95% UV Blockage: The woven fabric significantly reduces harmful UV and lowers direct sunlight in shaded areas, making it practical for pools and patios.
• Breathable, Water-Permeable Weave: The mesh construction lets air and water pass through freely so rain does not pool and shaded areas remain cooler.
• Reinforced Edges and D-Rings: Double-layer stitched seams and stainless steel D-rings improve strength at attachment points for a more secure installation.
• 3 Year Limited Warranty: The product includes a warranty that offers reassurance under normal weather and use.

Who It's For

This shade sail is best suited for homeowners or small businesses in sunny climates who need a heavy duty, long-lasting solution for patio, balcony or pool shading. The right triangle shape is ideal when one corner must anchor close to a wall, house or narrow space while still covering a wide area.

People who need a fully weatherproof, rigid canopy or those who prefer solid waterproof canopies should look elsewhere; this is a breathable, mesh fabric designed to block sun and allow water through rather than keep rain out entirely.
