ShadeMart 11ft x 22ft Brown Sun Shade Sail Rectangle - UV Resistant

In this review of the ShadeMart 11' x 22' Brown Sun Shade Sail rectangle canopy, the bottom line is simple: it is a practical, heavy duty shade solution for homeowners who need affordable UV protection for patios, carports, pools or outdoor equipment. The reviewer found the woven HDPE fabric and stainless steel corner D rings deliver durable performance and strong anchoring, while the breathable, water permeable design reduces temperature beneath the sail. If you want a customizable rectangle sail that blocks sunlight without trapping heat, this shade sail is worth considering.

Key Features

• Woven HDPE fabric: provides a durable, tear-resistant surface that blocks up to 95% of harmful UV rays while remaining breathable.
• Stainless steel D rings: attached to heavy duty white webbing for secure anchoring and reliable long-term attachments to posts or walls.
• Water and air permeable: allows rainfall and airflow to pass through, preventing pooling and reducing heat buildup under the canopy.
• Custom sizing available: a range of custom sizes can be ordered so the sail can be tailored to specific patio, carport or pergola dimensions.
• Rectangle styling: a clean rectangular shape that integrates with existing outdoor design and serves both functional and decorative roles.
• Wide applications: can be mounted to poles, trees, walls or roofs to protect patios, pools, equipment or seating areas.

Who It's For

The ShadeMart rectangle shade sail is best for homeowners and renters who need an economical way to reduce sun and heat on patios, over pools, carports or outdoor cooking areas. It suits DIY installers who can measure their space accurately and attach the sail to existing structures or with a hardware kit.

Those who need a fully waterproof canopy or a rigid permanent roof should look elsewhere, as this style is intentionally water permeable and optimized for ventilation rather than complete rain protection. Larger commercial installations that require certified structural systems may also prefer purpose-built architectural solutions.
