ShadeMart 16 ft x 17 ft Green Rectangle Shade Sail - Breathable UV

In this review the ShadeMart 16' x 17' Green Sun Shade Sail is examined for homeowners and light commercial users who need a durable, breathable canopy that reduces temperature and blocks UV. The single biggest reason to buy is its woven HDPE fabric that combines strong stitching and stainless steel D rings to create a robust, water-permeable cover that blocks up to 95% of harmful UV rays while allowing airflow. The reviewer found it especially useful where airflow and sun protection are required without trapping heat under the canopy.

Key Features

• Woven HDPE fabric: provides durable, tear-resistant coverage that reduces surface temperatures and withstands regular outdoor exposure.
• Stainless steel corner D rings: securely anchor the sail and are attached to heavy duty white webbing for dependable tension points.
• Water permeable construction: lets rain and air pass through, preventing water pooling and lowering wind load on the attachment points.
• High UV blockage: blocks up to 95% of harmful UV rays and significantly lowers ambient temperature beneath the sail.
• Custom sizing available: multiple size options and custom orders make it adaptable for patios, carports, pools, and pergolas.
• Decorative rectangle shape: integrates with existing outdoor design and can be used to define seating or shade areas.

Who It's For

The ShadeMart 16' x 17' rectangle is aimed at homeowners, renters with outdoor spaces, and small businesses that want effective sun protection without installing a permanent roof. It fits well over patios, carports, pool equipment, or seating areas where airflow and UV protection are priorities.

Those who need a fully waterproof canopy or require rigid structural shelter should look elsewhere; this style is explicitly not waterproof and is intended as a breathable shade solution rather than a rainproof roof.

Pros & Cons

Pros

• Durable HDPE weave and reinforced stitching deliver reliable longevity and material strength.
• Stainless steel D rings and heavy webbing make installation secure when proper hardware is used.

• Permeable design prevents water pooling and reduces wind stress on anchors.

Cons

• Not waterproof, so it will not keep an area dry in heavy rain.
• Manual sizing can vary slightly; accurate measuring is required before ordering.

Specifications
