ColourTree Custom Size 18ft x 19ft x 26.2ft Right Triangle Shade Sail

Our review of this ColourTree custom size right triangle sun shade sail finds it best suited for homeowners who need a large, durable canopy to reduce heat and UV exposure over patios, pools or carports. The single biggest reason to buy is the heavy 190 GSM virgin HDPE fabric treated with a UV stabilized compound, which the reviewer found feels thicker and more robust than thinner recycled sails and is designed to resist fading and sun damage over time.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric gives a noticeably substantial feel and is tested to resist UV degradation longer than recycled material.
• UV stabilized compound: Factory treatment reduces drying, tearing and fading so the canopy maintains color and strength after extended sun exposure.
• 95% UV blockage: The woven fabric blocks the majority of harmful UV rays and lowers temperature in the shaded area for more comfortable outdoor use.
• Breathable design: Breathable weave allows air and rainwater to pass through, preventing water pooling and reducing wind uplift compared with solid covers.
• Reinforced edges and D-rings: Double layered stitched seams and stainless steel D-rings create stronger anchor points for durable installations.
• 3 year limited warranty: Warranty provides added confidence in normal weather and usage situations.

Who It's For

This shade sail is a practical choice for people fitting a custom large triangular cover over a patio, above-ground pool, carport or backyard seating area who want a heavy duty fabric with strong UV protection. The large listed dimensions make it useful where a single, continuous shade area is preferable to multiple smaller sails.

Those who need a ready-to-hang kit should look elsewhere: installation hardware is sold separately and each D-ring requires a non-nylon cable rope and suitable anchors. Buyers seeking a very lightweight, inexpensive short-term cover may also prefer thinner, lower GSM alternatives.

Pros & Cons

Pros

• Thick 190 GSM virgin HDPE feels durable and resists sun damage better than recycled fabrics.

• Breathable weave prevents water pooling and performs well in light rain.

Cons

• Size must be measured carefully; customers report mixed experiences with fit and some sizing issues.
• Hardware is not included, so total installation cost and effort are higher.
