ColourTree Custom Size Right Triangle Sun Shade Sail 13ft x 18ft x

In this review the ColourTree custom size right triangle sun shade sail is examined for homeowners and light commercial users who need a durable, UV-blocking canopy. The bottom line: this shade sail is best for outdoor spaces that require a thick, breathable fabric that resists fading and reduces temperature, with its standout feature being the 190 GSM 100% virgin HDPE material treated with UV stabilized compound. If longevity in sun exposure and strong, reinforced corners matter most, this review explains why this model is worth considering.

Key Features

• 190 GSM Virgin HDPE: The thick 190 GSM construction uses 100% virgin HDPE for greater strength and longer outdoor life compared to recycled fabrics.
• UV Stabilized Compound: The fabric was lab tested for prolonged UV exposure and treated so it resists drying, tearing and fading for extended performance.
• 95% UV Blockage: The woven material blocks up to 95% of harmful UV, helping to lower temperature and protect people and furniture beneath the sail.
• Breathable, Water-Permeable Design: The weave allows air and water to pass through so rain does not pool and ventilation reduces heat under the sail.
• Reinforced Edges and Corners: Double layered stitched seams and stainless steel D-rings with extra heavy stitching give reliable attachment points and reduce fraying.
• Warranty: A 3 year limited warranty is included for normal weather and use, giving added purchase reassurance.

Who It's For

This shade sail suits homeowners, pool owners, and small commercial settings that need a heavy duty, long-lasting canopy to cut sun and heat. Its right triangle 13' x 18' x 22.2' configuration is useful for patios, above-ground pools, carports, balconies and garden seating areas where a triangular coverage fits between three anchor points.

It is not ideal for buyers who need a full kit with mounting hardware included, as attachment cables and hardware are sold separately and proper installation requires stainless or steel cables rather than nylon rope. Also, those looking for a very large continuous shade field should consider multiple sails or different shapes rather than a single triangle this size.

Pros & Cons

Pros

• High thickness and virgin HDPE offer improved durability and resistance to UV damage.
• Blocks up to 95% of UV while remaining breathable to prevent water pooling and reduce heat.
• Well-constructed edges and stainless steel D-rings make for sturdy, dependable anchoring.

Cons

• Customers report mixed durability in real use, with some experiencing tearing under heavy conditions, so installation and tensioning matter.
• Hardware and cables are not included and must be purchased separately for proper installation.
