Right Triangle 7 ft x 11 ft x 13 ft Grey Sun Shade Sail - Heavy Duty

In this review the Right Triangle 7 ft x 11 ft x 13 ft sun shade sail is evaluated for homeowners and small commercial installs who need a durable, breathable canopy that blocks strong sunlight without trapping heat. The biggest reason to buy is its heavy-duty 200 GSM HDPE fabric with UV inhibitors and a 3 year warranty, which delivers reliable shade and long-term resistance to fading and degradation while still allowing airflow. The sail is designed with curved edges measured corner-to-corner so it stays tight and neat after installation rather than sagging in the middle.

Key Features

• Measurement system: Corners are measured corner-to-corner and edges are slightly curved to produce a tight, neat installation that minimizes mid-span sagging.
• Durable material: Made from 100% 200 GSM HDPE fabric that blocks up to 95% of harmful UV while remaining breathable so water and breeze pass through.
• Finished edges: Heavy duty double-layer reinforced stitched seams prevent fraying and preserve shape under regular tension.
• Stainless hardware: Each corner includes a stainless D ring with extra stitched reinforcement to secure attachment points and improve longevity.
• Warranty: Includes a 3 year UV degradation warranty, offering confidence the fabric resists fading and sun damage under normal weather conditions.

Who It's For

This shade sail suits homeowners, cafes, dog owners and small commercial spaces that need a robust triangular canopy for patios, play areas or parking shade where airflow and UV protection are priorities. Its breathable HDPE makes it a good pick when preventing pooling water and reducing wind load are important.

Those who need exact straight-edged geometry or an unusually sized panel should consider a custom order or a different product; the standard design intentionally uses a calculated radian curve to ensure the best tensioned appearance once installed.
