ShadeMart 6 ft x 17 ft White Rectangle Sun Shade Sail - Breathable

Our review of the ShadeMart 6 ft x 17 ft White Rectangle Sun Shade Sail finds it best for homeowners and small-business owners who need a durable, breathable canopy that cuts heat and UV without trapping water. The single biggest reason to buy is its practical woven HDPE fabric that blocks up to 95% of harmful UV while remaining water permeable, so outdoor areas stay cooler and resist pooling after rain. Installation is straightforward when paired with proper hardware, and the stainless steel D rings plus heavy webbing make it feel built to last.

Key Features

• MATERIAL: Woven HDPE fabric provides a balance of strength and breathability so the sail resists tearing while allowing air and water to pass through.
• UV PROTECTION: The canopy blocks up to 95% of harmful UV rays, significantly reducing temperatures beneath the sail for more comfortable outdoor use.
• HARDWARE: Stainless steel corner D rings attached to heavy white webbing give secure anchor points that handle tension and repeated use.
• WATER MANAGEMENT: The fabric is water permeable and breathable, preventing water pooling and reducing wind load compared with solid, waterproof covers.
• CUSTOM SIZE OPTIONS: ShadeMart offers multiple custom sizes so you can choose dimensions that best fit patios, carports, or poolside areas when measured accurately.
• STYLING: The clean rectangle shape and white color act as a neutral design element that integrates with many outdoor schemes and brightens shaded areas.

Who It's For

This shade sail suits homeowners, renters with outdoor patios, and small businesses needing a cost-effective way to lower temperatures in seating or parking areas. It is especially useful where airflow and drainage are desired because the fabric is water permeable and breathable.

People who need a fully waterproof canopy or an exact factory-cut geometric rectangle for precision installs should look elsewhere; the product can vary slightly with manual measurements and is explicitly not waterproof.

Pros & Cons
