ColourTree Custom Size 20ft x 23ft x 30.5ft Blue Right Triangle Sun

In this review of the ColourTree custom Right Triangle sun shade sail, the bottom line is simple: it is for homeowners and small businesses who need a durable, high-coverage shade solution that stands up to strong sun and stormy conditions. The single biggest reason to buy is its 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which delivers long-lasting UV protection and durability not commonly found in recycled-material sails. For patios, pools, carports and other outdoor seating areas, this sail provides reliable shade and breathability.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric offers improved tear resistance and longevity compared to recycled alternatives after prolonged sun exposure.
• UV stabilized compound: Laboratory-tested to resist drying, fading and fabric failure, extending usable life under strong sunlight.
• 95% UV blockage: Significantly reduces temperature and harmful UV in the shaded area, making it practical for patios, pools and play areas.
• Breathable woven fabric: Allows air and water to pass through so rain does not pool and shaded areas remain ventilated and cooler.
• Reinforced construction: Double layered stitched seams and extra heavy stitching at corners keep shape and secure stainless steel D-rings for reliable mounting.
• Custom size made to order: This right triangle sail is produced to the specified 20' x 23' x 30.5' dimensions and is typically made in 3-7 business days.

Who It's For

This shade sail is ideal for homeowners, rental property managers and small commercial venues that need a robust shade solution with long-term UV resistance. It suits locations where wind and occasional storms occur, since customers report the sail surviving severe weather when properly installed, and the heavy stitching and stainless D-rings support durable attachment.

It is less appropriate for buyers who want an off-the-shelf short-term decorative cover or those who need an impermeable rain canopy; the woven fabric is intentionally breathable to avoid pooling rather than provide full waterproof protection. Installation hardware is sold separately, so buyers who expect an all-in-one kit should plan to purchase compatible ColourTree hardware or similar heavy-duty fittings.

Pros & Cons

Pros

• High-quality 190 GSM virgin HDPE fabric provides strong UV resistance and durability.
• Breathable design prevents water pooling and helps reduce shaded area temperature.
• Heavy stitched edges and stainless steel D-rings make for secure, long-lasting mounting.

Cons

• Hardware and cables are required but sold separately, so additional purchases are needed for installation.
• Not fully waterproof by design; it sheds water rather than provide complete rain protection.
