ColourTree Custom Size 11ft x 12ft x 16.3ft Right Triangle Shade Sail

Our review looks at the ColourTree custom right triangle shade sail and concludes it is a strong choice for anyone needing heavy-duty sun protection with exact sizing. Built from 190 GSM 100% virgin HDPE and treated with UV stabilized compound, this shade sail's single biggest advantage is long-term durability and reliable 95% UV blockage, making it especially suitable for patios, pools, balconies and carports where heat and sun damage are concerns.

Key Features

• 190 GSM virgin HDPE fabric: Provides a thicker, more durable weave than recycled alternatives and resists tearing under prolonged sun exposure.
• UV stabilized compound: The fabric resists drying out, fading and brittleness after extended UV exposure, extending usable life.
• 95% UV blockage: Significantly reduces heat and harmful sunlight in the shaded area for cooler, more comfortable outdoor use.
• Breathable woven design: Allows air and water to pass through so rain does not pool and ventilation remains good beneath the sail.
• Reinforced edges and stainless D-rings: Heavy double-layer seams and stitched corners with stainless steel D-rings improve attachment strength and reduce fraying.
• Three year limited warranty: Manufacturer warranty covers normal weather and use, adding confidence for longer-term installations.

Who It's For

This shade sail suits homeowners and small businesses who need a custom-sized right triangle sail for a specific area, such as a pool corner, patio cover or carport. Its heavy 190 GSM virgin HDPE fabric and UV stabilization make it a good match for locations with strong sun and high exposure where durability matters.

Those who should look elsewhere include buyers who need a full hardware kit included (hardware is sold separately) or users who prefer a completely waterproof awning rather than a breathable, shade-focused fabric that allows some water through.

Pros & Cons

Pros

• High-quality 190 GSM virgin fabric delivers better longevity and resistance to UV damage than recycled material.
• Blocks up to 95% of UV while remaining breathable, reducing heat without trapping moisture.
• Well-constructed edges and stainless steel D-rings make installation secure when proper hardware is used.
• Useful three year limited warranty offers reassurance under normal use.

Cons

• Installation requires separate hardware and suitable anchor points; buyers must purchase cables and fittings separately.
• Not fully waterproof by design, so it will not keep out heavy driving rain as a solid canopy would.

Frequently Asked Questions

Do I get installation hardware with the sail?
No, installation hardware kits and cables are sold separately; each D-ring requires a cable and quality fittings for a secure mount.

Is the fabric waterproof?
No, the woven HDPE is breathable and allows water to pass through so it will not pool but is not fully waterproof like a solid tarp.

How long will the sail last in sun?
The 190 GSM virgin HDPE is UV stabilized and lab tested for extended exposure; a three year limited warranty is provided under normal use.
