ColourTree Custom Size 13 ft x 20 ft x 23.9 ft Grey Right Triangle

Our review of this ColourTree custom-size right triangle shade sail finds it best for homeowners or small businesses needing a heavy-duty, color-stable canopy for patios, pools, or carports. The single biggest reason to buy is the fabric: a 190 GSM 100% virgin HDPE material treated with UV stabilized compound that proved its durability in long-term UV testing, which translates to fewer replacements and reliable sun protection. Installers should plan for separate hardware and proper corner rigging to get a neat, long-lasting fit.

Key Features

• 190 GSM virgin HDPE: thick, non-recycled material gives stronger tear resistance and longer life under sun exposure than common recycled fabrics.
• UV stabilized compound: the treatment helps prevent drying, tearing and fading so the canopy keeps its shape and color over seasons.
• 95% UV blockage: the woven fabric significantly reduces UV sunlight and lowers temperatures beneath the sail for more comfortable outdoor use.
• Breathable weave: allows water and air to pass through so rain does not pool and the canopy resists wind uplift better than solid covers.
• Reinforced edges and hardware: double layered stitched seams and stainless steel D-rings create strong anchor points for secure mounting.
• 3 year limited warranty: provides reasonable coverage under normal weather and use for added buyer confidence.

Who It's For

This shade sail is ideal for homeowners with a designated corner or triangular mounting layout, people who want a long-lasting shade solution for a patio, balcony, or pool area, and small commercial spaces that need reliable UV protection without frequent replacement. The heavy 190 GSM fabric and stainless steel D-rings suit sites exposed to strong sun and regular use.

It is less suitable for buyers who expect a full hardware kit with purchase, since installation kits and cables are sold separately, or for those who need a waterproof solid canopy rather than a breathable shade sail that allows water through.

Pros & Cons

Pros

• Excellent sun protection from the 95% UV blockage fabric for cooler shaded areas.
• Durable construction thanks to 190 GSM virgin HDPE and reinforced stitched seams.
• Stainless steel D-rings and strong stitching make attachment points robust under tension.
• Breathable design prevents water pooling and improves wind performance compared with solid covers.

Cons

• Installation hardware and cables are required but sold separately, so total cost and planning are higher than a plug-and-play kit.
• As a woven shade sail it is not fully waterproof, which may not suit users wanting complete rain protection.

Our Verdict

For anyone who needs a heavy-duty shade sail that resists fading and tearing, this ColourTree right triangle canopy offers clear value thanks to its thick 190 GSM virgin HDPE and reinforced construction.
