ColourTree Custom Size Right Triangle Sun Shade Sail 12ft x 17ft x

Our review of the ColourTree custom size right triangle sun shade sail focuses on people who need a heavy duty, long-lasting canopy for patios, pools, carports or balconies. The standout reason to buy is the fabric: a dense 190 GSM 100% virgin HDPE that was UV tested for extended outdoor life and claims up to 95% UV blockage. In practical use this sail reduces heat and glare while remaining breathable so water passes through, and its reinforced edges and stainless steel D-rings make it noticeably sturdier than lighter recreational alternatives.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric gives the sail greater tear resistance and a longer service life under strong sun exposure.
• UV stabilized compound: Laboratory-tested UV protection prevents drying, fading and premature wear so the sail keeps its strength longer outdoors.
• 95% UV blockage: Dense woven construction cuts most harmful UV, lowering temperatures and protecting shaded areas and occupants.
• Breathable fabric: The weave allows air and rainwater to pass through, preventing pooling and reducing wind stress on attachment points.
• Reinforced seams and D-rings: Double layered stitched edges and stainless steel D-rings provide strong anchor points and resist fraying.
• Three year warranty: A limited warranty covers the sail under normal weather and use, offering added confidence in the purchase.

Who It's For

The sail is best for homeowners and small businesses that want a heavy duty, commercial-grade shade solution for a specific corner or area where a right triangle shape fits, such as a patio corner, poolside cover or carport. It suits users who prefer durable materials and reduced long-term fading from UV exposure.

It is less suitable for those who need an all-in-one mounting kit, since installation hardware is sold separately and proper cables and fittings are required for best results. If you need a very small, temporary or decorative sail, a lighter recreational product may be a better match.
