ShadeMart 19 ft x 19 ft Green Sun Shade Sail UPF50 Square - Heavy Duty

In this review the ShadeMart 19' x 19' green sun shade sail is evaluated as a heavy duty outdoor canopy for patios, carports and RV covers. The bottom line: it is a practical choice for anyone who needs reliable UV protection and airflow without trapping moisture, since the woven HDPE fabric blocks up to 95% of UV while remaining water and air permeable. Installation is straightforward with the stainless steel D rings and white webbing, and the sail's durability and build quality make it worth considering for seasonal and long term shade projects.

Key Features

• Material: Woven HDPE fabric provides strong, tear-resistant coverage while remaining breathable for hot days.
• UV Protection: Blocks up to 95% of harmful UV rays, which helps lower ambient temperatures by roughly 10-15 degrees under the canopy.
• Water & Air Permeable: Designed to allow rain and wind to pass through so it does not collect water or act like a sail in breezy conditions.
• Hardware: Stainless steel corner D rings attached to heavy duty white webbing give secure anchor points and resist corrosion outdoors.
• Custom Sizing: Available in multiple sizes, including custom options, so it can be tailored to patios, pergolas, carports or pool areas.
• Styling: Rectangular shape and color choices let the sail integrate with existing outdoor decor while providing functional shade.

Who It's For

The ShadeMart sun shade sail is well suited to homeowners and renters who want a durable, breathable canopy to reduce sun exposure for patios, RVs, pools and carports. It is especially useful where ventilation and drainage matter, since the fabric is not waterproof but does prevent UV and lower temperatures effectively.

It is less appropriate for buyers who need a fully waterproof shelter or an exact color match guaranteed; customer feedback shows mixed opinions on color accuracy and the product is explicitly not waterproof, so those needing rain protection should look at covered canopies or waterproof awnings.

Pros & Cons

Pros

• Blocks high levels of UV and noticeably cools shaded areas.
• Breathable, water-permeable fabric prevents pooling and reduces wind strain.
• Sturdy stainless steel D rings and heavy webbing give secure attachment points.
• Easy to install and holds up well in strong winds according to users.

Cons

• Not waterproof, so it will not provide full rain protection.
• Some customers report the color differs from expectations and size listings may vary slightly due to manual measurements.
