ColourTree CTSLR Custom Size 13ft x 21ft Red Sun Shade Sail Canopy

In this review of the ColourTree CTSLR 13' x 21' red sun shade sail, the bottom line is simple: it is built for people who need reliable, heavy-duty UV protection over patios, pools, and carports. The single biggest reason to buy is the thick 190 GSM virgin HDPE fabric that has been UV stabilized and lab tested, which delivers long-lasting sun blockage and reduced heat beneath the canopy. This review looks at durability, ease of installation, and day-to-day performance for homeowners and small commercial installs.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric is designed to resist fading and tearing and performed in extended UV testing to increase lifespan.
• 95% UV blockage: The woven fabric blocks most harmful UV rays and helps lower temperatures in the shaded area, making it useful for patios and poolside lounging.
• Breathable weave: The construction allows air and water to pass through so rain does not pool and the shaded space stays cooler and ventilated.
• Reinforced edges and hardware-ready corners: Double layered stitched seams and stainless steel D-rings improve load distribution and attachment strength for a secure installation.
• UV stabilized compound: Additive in the material helps prevent the fabric from drying out in sun exposure, reducing brittle failures over time.

Who It's For

The ColourTree CTSLR is a good fit for homeowners, small business owners, and landscapers who need a dependable shade solution for patios, balconies, carports, or pool areas and who value a product made from 100% virgin HDPE for longer UV resistance. It also suits anyone who prefers breathable shade that reduces heat without blocking airflow.

It is less suited to buyers who need a fully waterproof canopy for prolonged wet-weather coverage or who want a complete hardware and rope kit included; installation hardware is sold separately and synthetic ropes that stretch or degrade should be avoided according to the instructions.

Pros & Cons

Pros

• Durable 190 GSM virgin HDPE feels substantial and resists sun-related degradation better than recycled fabrics.
• High UV blockage significantly reduces sunlight and lowers temperature in shaded areas.
• Reinforced seams and stainless steel D-rings make mounting secure and long-lasting when paired with proper hardware.
• Breathable weave prevents water pooling after rain and improves airflow beneath the sail.

Cons

• Installation requires separate hardware and proper cable selection; nylon ropes are discouraged and not included.
• While water passes through the fabric, it is not a fully waterproof canopy for continuous heavy rain protection.
