11ft x 16ft White Sun Shade Sail Rectangle - UPF50 Outdoor Canopy

Our review of the ShadeMart 11' x 16' White Sun Shade Sail finds it best suited for homeowners and small businesses who need durable, breathable sun protection for patios, carports, pools or pergolas. The single biggest reason to consider this shade sail is its woven HDPE construction with stainless steel D rings and reinforced webbing, which delivers reliable sun protection and long-term durability while remaining breathable and water permeable.

Key Features

• MATERIAL: Woven HDPE fabric provides a strong, tear-resistant canopy that stands up to outdoor exposure.
• UV PROTECTION: Blocks up to 95% of harmful UV rays, helping lower temperatures under the sail by roughly 10 to 15 degrees for a cooler sitting area.
• HARDWARE: Stainless steel corner D rings attached to heavy duty white webbing offer secure attachment points when used with appropriate hardware kits.
• BREATHABILITY: Water permeable weave allows rain and air to pass through so the sail does not trap water and reduces wind load on the fabric.
• CUSTOM SIZE OPTION: Available in a range of custom sizes so you can match nonstandard areas-measure the venue carefully before ordering.

Who It's For

This shade sail is ideal for backyard patios, carports, poolside lounges and pergolas where UV protection and airflow are priorities; it works well attached to poles, trees, walls or roofs with the proper hardware. Installers who prefer a breathable, non-waterproof canopy that lowers ambient temperature and withstands regular outdoor use will appreciate its construction.

Those who need a fully waterproof cover, a precisely engineered rectangle with machine-perfect dimensions, or an indoor fabric should look elsewhere; the weave is intentionally permeable and sizes may vary slightly due to manual measurement and cutting.

Pros & Cons

Pros

• Durable woven HDPE material and stainless steel D rings provide long-lasting performance and secure mounting.
• Blocks up to 95% of UV rays and can noticeably reduce heat under the canopy.
• Breathable, water permeable design prevents water pooling and reduces wind strain on the fabric.

Cons

• Not waterproof, so it will not provide full rain protection in heavy storms.
• Size and shape can vary slightly due to manual measurement and cutting, which may affect perfectly rectangular installations.
