ColourTree CTSLR Custom Size 6 ft x 18 ft White Sun Shade Sail Canopy

Our review of the ColourTree CTSLR 6 ft x 18 ft white sun shade sail finds it best for homeowners and small commercial sites who need reliable UV protection and a durable, breathable fabric. The single biggest reason to buy is its 190 GSM 100% virgin HDPE construction treated with a UV stabilized compound, which the manufacturer says was lab tested for long UV exposure and produces a noticeably thicker, longer lasting sail compared with recycled alternatives. The result is a shade that reduces heat and sun exposure while remaining breathable and resistant to routine weather.

Key Features

• 190 GSM Virgin HDPE: The thick, non-recycled fabric is built to last and was lab tested for extended UV exposure, improving long-term durability.
• 95% UV Blockage: The woven fabric blocks most harmful UV rays, helping lower temperature and sun damage in shaded areas like patios or pools.
• Breathable Design: Breathable weave allows water and air to pass through, preventing pooling and reducing wind stress.
• Reinforced Edges: Double layered stitched seams and heavy stitching at corners help prevent fraying and keep the sail square over time.
• Stainless Steel D-Rings: Each corner includes a D-ring for secure attachment and simpler installation when used with proper hardware.
• 3 Year Warranty: The product includes a limited 3 year warranty under normal weather and use for buyer reassurance.

Who It's For

This shade sail is ideal for homeowners with patios, pools, balconies or carports who want a durable, breathable canopy that reduces sun and heat. It also fits small commercial installations where a heavy duty, UV resistant fabric is preferred over thin or recycled alternatives.

Those who need integrated installation hardware should look elsewhere or purchase a dedicated shade sail hardware kit, because the sail ships without mounting kits and requires cables and proper fittings for best performance.

Pros & Cons
