21ft x 24ft x 31.9ft White Right Triangle Sun Shade Sail - 190 GSM

In this review we look at the 21ft x 24ft x 31.9ft white right triangle sun shade sail that is made to order for larger patios and poolside areas. The bottom line: this shade sail is for homeowners or commercial users who need broad, durable UV protection with a breathable fabric; its single biggest selling point is the 190 GSM 100% virgin HDPE construction that is lab tested for extended UV resistance. The review covers how it performs in sun and wind, how it installs, and whether it is good value for long-term outdoor shading.

Key Features

• 190 GSM Virgin HDPE: The thick, non-recycled fabric is designed to resist tearing and deterioration for longer life under constant sun exposure.
• UV Stabilized Compound: The material has been lab tested for extended UV resilience, helping the sail resist fading and drying out over time.
• 95% UV Blockage: The woven fabric blocks the vast majority of harmful UV, reducing temperature and sunlight in the shaded area for patios, pools, and carports.
• Breathable Weave: Air and water pass through the mesh to prevent pooling and reduce wind sail forces, so it performs well in mixed weather.
• Reinforced Construction: Double layered stitched seams and heavy stitching at corners with stainless steel D-rings make the structure robust for repeated tensioning.
• Custom Made: This size is made to order in 3-7 business days and includes a 3 year limited warranty under normal use.

Who It's For

This right triangle sail is best for homeowners, small commercial venues, and outdoor living spaces that need a large, tailored shade footprint in white to blend with landscaping or modern architecture. It suits pools, patios, play areas, and carports where reduced heat and strong UV blockage are priorities.

It is not ideal for buyers who need a quick off-the-shelf replacement or who prefer a non-breathable waterproof canopy; hardware kits are required but sold separately, so customers who want a full mounting solution included should plan to purchase a recommended hardware set and cables.

Pros & Cons
