ShadeMart 11ft x 17ft Red Rectangle Sun Shade Sail - UPF50 Protection

Our review of the ShadeMart 11' x 17' Red Rectangle Sun Shade Sail finds it best suited for homeowners and small businesses who want effective sun protection and a durable, breathable canopy for patios, carports, and pool areas. The biggest reason to buy is its combination of woven HDPE fabric and stainless steel D rings, which delivers robust UV protection and long-term outdoor performance while remaining water permeable so rain does not pool on the fabric.

Key Features

• Material: Woven HDPE fabric provides a strong, tear-resistant surface that resists fading and fraying in sun-exposed settings.
• Hardware: Stainless steel corner D rings attached to heavy duty white webbing make anchoring secure and help the sail survive high wind events.
• UV Protection: Blocks up to 95% of harmful UV rays, lowering surface and air temperature beneath the sail for cooler outdoor comfort.
• Breathability: Water permeable and breathable construction allows rain and wind to pass through so water does not pool and airflow is maintained.
• Custom Sizing: Available in a range of custom sizes so buyers can match unusual venues, with the fabric area kept consistent despite manual measurement variance.

Who It's For

The ShadeMart rectangle shade sail is ideal for homeowners, renters, or small commercial spaces that need a durable, decorative sun screen over patios, carports, pergolas, or play areas. Installers who want a breathable canopy that reduces heat and resists sun damage will appreciate the heavy duty webbing and stainless steel D rings for solid attachment points.

It is not intended for use as a waterproof cover or standing-roof solution; if you need complete rain protection or an enclosed awning, look for a waterproof canopy instead. Also, buyers who require perfectly exact geometric precision should allow for slight variation from manual measurement when ordering custom sizes.

Pros & Cons

Pros

• Durable woven HDPE fabric and stainless steel D rings deliver long service life and reliable anchoring.
• Effective sun protection, blocking up to 95% of UV and noticeably lowering temperatures below the sail.
