ShadeMart 9 ft x 17 ft Blue Rectangle Sun Shade Sail - UPF50

In this review of the ShadeMart 9 ft x 17 ft Blue Rectangle Sun Shade Sail, the bottom line is simple: this is a durable, breathable sun screen best for patios, carports and poolside spots where strong UV protection and airflow matter. The sail is made from woven HDPE and blocks up to 95% of harmful UV rays while remaining water permeable, so it lowers temperatures noticeably without collecting standing water. For anyone wanting a heavy duty, low-maintenance shade solution that doubles as an aesthetic canopy, this sail is worth considering.

Key Features

• Woven HDPE fabric: provides a tough, tear-resistant surface that stands up to repeated outdoor exposure while remaining lightweight to handle.
• UPF50 sun protection: blocks up to 95% of UV rays, helping reduce surface and ambient temperatures under the sail by around 10 to 15 degrees.
• Water permeable design: allows rain and air to pass through so the sail does not pond water or balloon in ordinary storms.
• Stainless steel D rings and webbing: heavy duty corner hardware attached to white webbing makes it easy to tension and secure the sail to fixed points.
• Custom sizing available: ShadeMart offers a range of sizes and will customize sails, which helps fit unusual patios or carports when measured accurately.
• Rectangle styling: a clean geometric shape that functions as both practical shade and a simple decorative element for yards or pergolas.

Who It's For

The ShadeMart rectangle shade sail is best for homeowners and small businesses who need reliable UV protection over mid-sized outdoor areas such as patios, carports, pool decks or market stalls. It is especially useful where airflow and drainage are desirable because the material is water permeable and breathable.

It may be less appropriate for buyers who need a fully waterproof canopy or who require an exact machine-cut geometry without any manual measurement variance. Also, anyone needing an instant plug-and-play mounting system should plan to buy proper hardware kits separately.

Pros & Cons

Pros

• High sun protection and noticeable temperature reduction under the canopy.
• Durable woven HDPE material with stainless steel D rings for secure anchoring.
• Breathable and water permeable, so rain drains through instead of pooling.
• Custom sizes available to fit a variety of installation needs.

Cons

• Not waterproof, so it will not keep an area dry in sustained rain.
• Some customers report minor size variation or non-perfect rectangles due to manual measurement.
