ColourTree CTSLT 10ft x 18ft x 20.6ft Brown Right Triangle Sun Shade

In this review the ColourTree CTSLT right triangle sun shade sail is evaluated for homeowners and small commercial spaces that need reliable UV protection and durable outdoor coverage. The bottom line: it is a heavy-duty, breathable shade made from 190 GSM 100% virgin HDPE that blocks up to 95% of UV, making it a strong choice for patios, pools and carports where long-term sun resistance matters. The review focuses on material performance, installation realities and whether it represents good value given its 3 year limited warranty.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric is designed to resist tearing and fading after extended UV exposure, offering a sturdier option than recycled alternatives.
• UV stabilized compound: Fabric was lab-tested for 20000 hours and treated to reduce drying out and prolong usable life under sunlight.
• 95% UV blockage: The woven mesh significantly cuts harmful UV and lowers temperatures in the shaded area, useful for patios, poolside and balconies.
• Breathable woven fabric: Air and water pass through the mesh so rain does not pool and the shaded area remains ventilated.
• Reinforced construction: Double layered stitched seams and stainless steel D-rings at corners improve attachment strength and prevent fraying.
• 3 year limited warranty: The sail is covered under normal weather and usage, offering some assurance of durability.

Who It's For

The ColourTree CTSLT sail is aimed at homeowners, pool owners and small businesses that need a robust, breathable shade with strong UV protection and prefer a non-recycled material for longevity. It suits installations using existing poles, trees or walls where stainless steel D-rings and cables can be attached for a tidy, tensioned fit.

It is less suitable for situations where a rigid, waterproof canopy is required or for customers who want a fully pre-fitted hardware kit included; installation hardware and cable rope must be purchased separately and care is needed to use appropriate metal fittings rather than nylon rope.

Pros & Cons

Pros

• High-quality 190 GSM virgin HDPE material that feels thicker and more durable than thinner sails.

• Solid edge construction and stainless steel D-rings make attachment straightforward and more secure when proper hardware is used.
• Breathable design prevents water pooling and keeps the shaded area ventilated.

Cons

• Some customers have reported mixed durability results, with a minority experiencing tearing, so expectations should be tempered for very exposed locations.
