ShadeMart 12 ft x 20 ft Brown Sun Shade Sail UPF50 Rectangle

In this review the ShadeMart 12 ft x 20 ft Brown Sun Shade Sail is evaluated for homeowners and small businesses who need reliable sun protection without a rigid structure. The bottom line: this rectangle sail is best for people who want a durable, breathable canopy that cuts heat and UV while remaining easy to mount. The review found the woven HDPE fabric and stainless steel D rings deliver solid durability and sun blocking, and the water permeable weave prevents pooling, making it a practical choice for patios, carports, and poolside areas.

Key Features

• MATERIAL: Woven HDPE fabric gives a strong yet flexible canopy that resists tearing and holds shape under tension.
• UV PROTECTION: UPF50-rated construction blocks up to 95% of harmful UV rays to significantly lower temperatures beneath the sail.
• WATER PERMEABLE: The breathable weave allows rainwater and airflow to pass through so there is no pooling and it dries quickly after storms.
• HARDWARE: Stainless steel corner D rings attached to heavy duty white webbing provide secure anchoring points for common installation kits.
• CUSTOM SIZE OPTION: Available in a range of custom sizes so buyers can choose a sail that better fits irregular spaces when measured accurately.
• STYLING: Rectangle shape and neutral brown finish integrate with many outdoor decors while providing a functional shade element.

Who It's For

This shade sail is ideal for homeowners with patios, pergolas, carports, or pool areas who want to reduce sun and heat without building a permanent roof. It suits do-it-yourselfers comfortable with basic mounting hardware and attaching sails to posts, walls, or trees using turnbuckles and eye straps.

Those who need a fully waterproof canopy or an exact factory-cut architectural rectangle should look elsewhere; this product is water permeable by design and manual measurements can produce slight size variation, so precise architectural installs may not be appropriate.

Pros & Cons

Pros

• Durable woven HDPE fabric provides long-term UV protection and resists tearing in normal outdoor conditions.
• Breathable, water permeable design prevents pooling and helps keep the shaded area noticeably cooler.
• Stainless steel D rings and heavy webbing make for secure, straightforward attachment to standard mounting hardware.
• Custom sizing options and neutral styling let it fit a variety of outdoor spaces.

Cons

• Not waterproof, so it will not keep out heavy rain and is intended primarily for shade rather than full weatherproofing.
• Some buyers report size variation and non-perfect rectangle edges due to manual measurements and cutting.

Frequently Asked Questions

Is this shade sail waterproof?
Answer. No, the fabric is water permeable and breathable so it allows water to pass through rather than providing a waterproof barrier.

Can it be installed on trees or poles?
Answer. Yes, with the proper hardware kits the corner D rings and webbing allow attachment to poles, trees, walls, or roof anchors.

Will it reduce temperature under the sail?
Answer. Yes, customers report noticeable cooling; the UPF50 fabric blocks sunlight and can lower temperatures beneath the canopy.
