Turquoise Rectangle Sun Shade Sail 17ft x 21ft - Custom Fit UPF50

Our review looks at the Turquoise Rectangle Sun Shade Sail sized 17' x 21' and built from 200 GSM HDPE fabric. This shade sail is aimed at homeowners and small commercial spaces who want a cooler, sun-safe outdoor area without a permanent structure; the single biggest reason to buy is its combination of high sun protection and durable construction, offering up to 95% UV blockage while remaining water and air permeable for long-term outdoor use.

Key Features

• 95% UV blockage: The 200 GSM HDPE material blocks up to 95% of harmful rays so outdoor areas stay safer from sun exposure.
• Temperature reduction: The shaded area can run up to about 15 degrees cooler than unshaded sections, making patios and play areas noticeably more comfortable.
• Commercial grade durability: Reinforced edges, double-layer stitching and stainless steel D-Rings help the sail withstand strong winds and extended outdoor use.
• Customizable fit: The sail is made to measured D-ring to D-ring dimensions so it can be tailored to awkward or unique installation points.
• Breathable, water-permeable fabric: The weave lets air and water pass through to prevent pooling and reduce wind load on mounting points.
• Three-year assurance: The included three-year assurance gives added confidence in the material and construction for multi-season use.

Who It's For

This shade sail suits homeowners, cafes, daycares and backyard hosts who need a flexible, semi-permanent canopy that cools and protects without blocking airflow. People who care about color options and a less intrusive look will appreciate the turquoise finish noted for holding color and resisting heavy fading.

It is less appropriate for buyers who need a rigid, waterproof shelter or a product rated for permanent roofing; while water and air permeable, this sail is designed to let moisture pass through rather than act as a full rain tarp.

Pros & Cons

Pros

• High UV protection up to 95% reduces sun risk for family and guests.
• Durable 200 GSM HDPE fabric with reinforced stitching and stainless steel D-Rings holds up in strong winds.
• Custom sizing delivers a close fit for nonstandard areas and easier tensioning.
• Breathable design lowers ambient temperature and prevents water pooling.

Cons

• Not fully waterproof, so it will not replace a solid awning in heavy rain.
• Custom measurements require careful D-ring to D-ring measuring to ensure the right fit.

Specifications

Our Verdict

The 17' x 21' turquoise shade sail is a practical choice for anyone wanting reliable sun protection and cooler outdoor spaces without building a permanent structure. Its heavy-duty 200 GSM fabric, reinforced construction and custom sizing make it good value for yards, patios and small commercial spots, though buyers who need complete rain protection should consider a solid canopy instead.

Frequently Asked Questions

Is this sail waterproof?
Answer. No, the fabric is water and air permeable so it drains and breathes rather than acting as a waterproof tarp.

How should I measure for a custom sail?
Answer. Measure D-ring to D-ring when the sail will be tensioned and allow recommended gaps at corners per installation guidance for best fit.

Can this sail handle strong winds?
Answer. The reinforced edges and stainless steel D-Rings provide commercial-grade durability and customers report it holding in very high winds when properly installed.
