ShadeMart 11ft x 22ft Rectangle Sun Shade Sail - Breathable UV

Our review of the ShadeMart 11' x 22' rectangle sun shade sail finds it best for homeowners and small businesses who want an inexpensive, durable way to cut heat and UV without building permanent structures. The bottom line: this woven HDPE sail is a practical, breathable cover that blocks up to 95% of harmful UV rays and reliably lowers temperatures by 10 to 15 degrees, making it a solid choice for patios, carports, pergolas and poolside equipment areas.

Key Features

• Material: The woven HDPE fabric is strong and resists tearing, providing long-term shading without feeling flimsy.
• UV protection: Blocks up to 95% of harmful UV rays, which helps reduce sun exposure and keeps shaded areas noticeably cooler.
• Breathable design: Water permeable and air permeable construction prevents pooling and allows airflow, reducing wind strain and heat buildup.
• Hardware ready: Stainless steel corner D rings attached to heavy duty webbing create secure anchor points for typical shade hardware kits.
• Custom sizing: A wide selection of custom sizes is offered so users can fit unusual spaces when they measure carefully before ordering.
• Decorative styling: The rectangular shape and multiple color options let the sail double as a design element for outdoor living spaces.

Who It's For

The ShadeMart rectangle sail is ideal for homeowners who need a removable, low-cost solution to shade patios, carports, pergolas, pool equipment or play areas. It fits people who prefer a breathable cover that reduces heat without obstructing airflow and who will install it with basic hardware or anchor points such as posts, trees, or walls.

It is less suitable for buyers seeking a fully waterproof canopy or a rigid permanent roof. Also, customers who need perfectly exact cut dimensions should measure carefully and expect small variations from manual measurement, though the sail's total fabric area remains consistent.
