11ft x 18ft x 21.1ft Green Right Triangle Sun Shade Sail - Heavy Duty

In this review the 11ft x 18ft x 21.1ft Green Right Triangle Sun Shade Sail is evaluated for homeowners and light commercial spaces seeking a durable, high-coverage shade solution. The bottom line: this sail is built from 190 GSM 100% virgin HDPE with UV stabilized compound, so its single biggest reason to buy is long-term sun resistance and strong fabric performance in hot, sunny climates. Installers who want breathable, 95% UV blockage and a finished, reinforced edge will appreciate the balance of protection and airflow.

Key Features

• 190 GSM Virgin HDPE: Thick, non-recycled fabric offers greater tear resistance and expected longevity compared to recycled alternatives.
• UV Stabilized Compound: Lab-tested for prolonged sun exposure, the material resists drying, fading and degradation for extended outdoor life.
• 95% UV Blockage: The woven fabric significantly reduces UV exposure and lowers temperatures beneath the sail for more comfortable outdoor use.
• Breathable Design: Permeable weave allows water and air to pass through so rain does not pool and airflow remains good under the canopy.
• Reinforced Edges & D-rings: Double-layer stitched seams and stainless steel D-rings provide durable attachment points and reduce fraying.
• 3 Year Limited Warranty: Warranty coverage under normal weather and usage gives added buyer confidence.

Who It's For

This shade sail suits homeowners, poolside settings, patios and small commercial outdoor seating areas looking for a large right triangle canopy that blocks most UV while allowing airflow. The green color and right triangle shape make it useful for corner coverage, carports or irregularly shaped outdoor spaces where a rectangular sail would not fit.

It is not intended for buyers who expect a waterproof shelter or for installations without proper hardware; this sail requires separate shade hardware and cable rope for secure mounting and will not perform as intended with lightweight nylon rope or without robust anchor points in wind-prone locations.

Pros & Cons

Pros

• High-quality 190 GSM virgin HDPE fabric that stood out to customers for durability and long-term sun performance.

• Professional finish with double-stitched edges and stainless steel D-rings for reliable mounting.

Cons

• Installation hardware is not included and requires additional purchase of proper cables and fittings for best results.

Frequently Asked Questions

Does this sail block most UV?
The fabric blocks about 95% of harmful UV, reducing sun exposure and cooling shaded areas.

Is installation hardware included?
No. Hardware kits and cable rope are required and sold separately; use wire cable rather than nylon rope for secure mounting.

Will water pool on the sail?
No. The breathable woven fabric allows water to pass through so pooling is unlikely when installed with proper slope.
