17 ft x 20 ft Sun Shade Sail Canopy Awning - Breathable UV Block

Our review of the 17' x 20' Sun Shade Sail Canopy finds it best suited for homeowners and small businesses who need a durable, breathable cover for patios, decks, carports or garden seating. The single biggest reason to buy is its combination of effective sun protection and airflow: the 185 GSM HDPE fabric blocks up to 95% of UV while allowing air and light to pass through, so shaded areas stay cooler without trapping heat. Installation is straightforward with included ropes and stainless steel D-rings, making this a practical choice for DIY outdoor shade projects.

Key Features

• Material: The 185 GSM 100% non-recycled HDPE fabric offers a balance of strength and breathability for long outdoor use.
• UV Protection: The fabric blocks 95% of UV rays, protecting people and furnishings from harmful sun exposure.
• Drainage and Airflow: Permeable construction allows water and air to pass through so rain does not pool and heat is not trapped underneath.
• Reinforced Edges: Double-layered, reinforced stitched seams prevent fraying and maintain shape under tension.
• Hardware Ready: Each corner has a stainless steel D-ring with heavy stitching and included polyethylene ropes to simplify mounting.
• Versatile Use: Designed for patios, pergolas, pools, gardens and carports where breathable shade and UV blocking are needed.

Who It's For

This shade sail is ideal for homeowners who want an affordable, heavy-duty cover for a patio, deck, pool area or carport where airflow and UV protection matter. It works well for DIYers who can attach the sail between trees, poles or walls using basic shade hardware.

People who need a precisely measured custom fit should take care: several customers note sizing can be off, so this product is less suited to projects requiring exact edge-to-edge coverage without adaptation or additional mounting adjustments.

Frequently Asked Questions

Will this sail trap heat under the canopy?
Answer. No, the permeable HDPE fabric is designed to allow air flow so it reduces heat buildup compared with solid canopies.

Does it come with installation hardware?
Answer. The sail includes polyethylene ropes and stainless steel D-rings; separate shade sail hardware kits or hooks are recommended for mounting to poles or walls.

Will water pool on the fabric in rain?
Answer. The breathable fabric allows water to pass through, so it resists pooling and sheds water more effectively than non-permeable covers.
