ShadeMart 11ft x 19ft Brown Rectangle Sun Shade Sail - Cool, UV50

In this review of the ShadeMart 11' x 19' Brown Sun Shade Sail the bottom line is simple: this rectangular HDPE canopy is best for homeowners and small businesses who need reliable sun and heat reduction on a budget. The reviewer found the fabric blocks harsh sunlight while remaining breathable and water permeable, so it lowers temperatures under the sail without pooling water. Installation is straightforward with the stainless steel D rings and heavy duty webbing, and customers who want a custom fit will appreciate that ShadeMart offers multiple sizes.

Key Features

• MATERIAL: Woven HDPE fabric provides durable, tear-resistant shade while staying lightweight for easier handling and installation.
• UV PROTECTION: The sail blocks up to 95% of harmful UV rays, reducing sun exposure and lowering temperatures in the shaded area.
• BREATHABILITY: Water permeable and breathable construction allows rain and air to pass through, preventing water pooling and reducing wind strain.
• HARDWARE READY: Stainless steel corner D rings attached to heavy duty white webbing make it simple to anchor the sail to posts, trees, or walls with the proper hardware kit.
• CUSTOM SIZING: A range of custom-sized sails is available so buyers can choose a fabric area that matches patios, carports, pergolas, or poolside spaces.

Who It's For

This shade sail is a good fit for homeowners, landscapers, and small commercial venues that need broad, reliable sun protection for patios, carports, pergolas, or pool areas. The breathable HDPE fabric and stainless steel fittings make it practical for outdoor use where airflow and UV blocking are priorities.

Shoppers who need a fully waterproof canopy, an exact precision rectangle without any manual measurement variance, or integrated mounting hardware should look elsewhere or plan to buy a separate hardware kit. Also, those wanting rigid shade structures or heavy insulation under the canopy may prefer a different product.
