ShadeMart 11ft x 22ft Grey Sun Shade Sail Rectangle - UV Blocking

Our review of the ShadeMart 11' x 22' Grey Sun Shade Sail finds it best suited for homeowners and DIY installers who want an affordable, heavy duty canopy to cut sun and lower temperatures over patios, carports or pools. The single biggest reason to buy is the fabric and construction: woven HDPE blocks up to 95% of harmful UV while remaining water and air permeable, so it shades effectively without collecting rain. Installation is straightforward with proper hardware, and the rectangle shape makes coverage predictable for common outdoor layouts.

Key Features

• Woven HDPE fabric: the high density polyethylene material provides strength and long-lasting shade while allowing airflow to keep the covered area cooler.
• Stainless steel D rings: corner rings are rust-resistant and securely attached to heavy duty white webbing for dependable anchor points.
• Water and air permeable: the sail allows water to pass through so it will not pool after rain and promotes airflow that reduces trapped heat.
• High UV protection: blocks up to 95% of harmful UV rays and can lower temperatures in the shaded area by roughly 10 to 15 degrees.
• Custom size options: multiple sizes are available so buyers can choose a sail to match a patio, pergola or carport layout precisely when measured correctly.
• Versatile mounting: with the right hardware kit the sail can be attached to trees, poles, walls or roofs for many outdoor applications.

Who It's For

This ShadeMart rectangle sail is ideal for homeowners, renters with outdoor space, and small business owners who need economical sun protection for patios, pool equipment, carports or outdoor seating. It appeals to people who prefer breathable shade that does not trap water or heat.

It is less suitable for buyers who need a fully waterproof canopy or for those seeking a freestanding umbrella-style shade; this model is permeable by design and intended to be mounted using existing structures or poles.

Pros & Cons

Pros

• Durable woven HDPE material with strong stitching that customers report holds up well.
• Stainless steel corner D rings and heavy webbing provide secure anchor points for a range of mounting options.
• Permeable design keeps rain from pooling and lowers temperatures under the sail.
• Good value compared with building permanent shade structures and easy to install for DIY projects.

Cons

• Not waterproof, so it will not keep an area completely dry during heavy rain.
• Size must be measured accurately before ordering since sails can vary slightly due to manual measurements.
