Right Triangle Sun Shade Sail 12ft x 20ft x 23.3ft Grey - Heavy Duty

In this review we look at the ColourTree right triangle sun shade sail sized 12ft x 20ft x 23.3ft, a heavy duty option for patios, pools and carports. The bottom line: this shade sail is for homeowners and small businesses who need reliable UV protection and long-lasting fabric performance; its single biggest reason to buy is the 190 GSM 100% virgin HDPE construction that was laboratory tested for UV durability, offering a thicker, more fade- and tear-resistant canopy than typical recycled sails.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled material gives the sail stronger resistance to tearing and drying out compared with recycled fabric.
• UV stabilized compound: Fabric treated to slow sun damage after laboratory testing up to 20000 hours, extending usable life under strong sun exposure.
• 95% UV blockage: Woven mesh blocks most harmful UV rays and reduces heat in the shaded area for patios, pools and outdoor seating.
• Breathable design: Open weave lets air and water pass through to prevent pooling and reduce wind load while keeping the space cooler.
• Reinforced edges and stainless D-rings: Double layered stitched seams and extra heavy corner stitching improve shape retention and make anchoring easier.
• Commercial grade build: Designed for demanding outdoor use and backed by a 3 year limited warranty for normal weather and usage.

Who It's For

The sail is ideal for homeowners, rental property managers, and small commercial spaces that need a durable shaded area over a patio, pool, balcony or carport. Buyers in sunny climates who prioritize long-term UV resistance and a breathable fabric that prevents water pooling will find the material and construction particularly useful.

Those who need a full mounting kit should note hardware is sold separately; customers who want a very decorative, tightly waterproof canopy or who prefer a different shape should consider other styles or supplementary fixtures, as this product is a breathable mesh right triangle focused on UV reduction rather than full rain protection.

Pros & Cons
