ShadeMart 11 ft x 22 ft Green Sun Shade Sail - UPF50 Rectangle

In this review of the ShadeMart 11' x 22' green sun shade sail the bottom line is practical: this rectangular HDPE canopy is for anyone who wants reliable UV protection and airflow for patios, carports or pool areas without creating a rainproof cover. The reviewer found the fabric's woven HDPE construction and stainless steel corner D rings make it a durable, low-maintenance solution that cuts sun and heat effectively while remaining breathable. If you need a heavy duty, customizable rectangle that reduces temperature and blocks sunlight, this is the sail to consider.

Key Features

• MATERIAL: Woven HDPE fabric provides long-term resistance to fading and tearing while remaining lightweight and stable in sun-exposed settings.
• UV PROTECTION: UPF-style blocking reduces harmful UV exposure by up to 95% and noticeably lowers ambient temperatures beneath the sail.
• BREATHABLE DESIGN: The water-permeable, breathable weave allows rain and air to pass through so water does not pool and cooling is improved.
• HARDWARE QUALITY: Stainless steel corner D rings and heavy duty white webbing reinforce attachment points for a secure installation when used with suitable hardware kits.
• CUSTOM SIZE OPTION: A range of custom sizes is available to match odd layouts, making it easier to cover patios, carports, pergolas, and poolside areas accurately.
• DECORATIVE VALUE: The rectangle shape and color options let the sail function as both practical shade and a visual upgrade for outdoor living spaces.

Who It's For

The ShadeMart rectangle sail is best for homeowners or small businesses wanting a durable, breathable canopy that prioritizes sun and heat reduction rather than full waterproofing. It suits patios, pergolas, carports and poolside seating where ventilation and UV protection are the primary goals.

It is less appropriate for buyers who need a fully waterproof shelter or an exact precision-cut rectangle without any manual measurement variance; customers should measure mounting points carefully and accept small dimensional variances common with custom fabric products.

Pros & Cons

Pros

• High UPF-style sun blocking that reduces heat and protects furnishings from sun damage.
• Durable woven HDPE fabric with stainless steel D rings and heavy webbing at corners for reliable anchor points.

• Custom sizing and multiple colors make it adaptable to many outdoor designs.

Cons

• Not waterproof, so it will not keep an area dry during heavy rain.
• Some customers report mixed experience with exact rectangular dimensions, so careful measurement is required.
