Sun Shade Sail 12 ft x 17 ft Terra Red Rectangle - Breathable UV Shade

In this review of the Sun Shade Sail 12' x 17' Terra Red rectangle canopy, the bottom line is simple: this is a practical, low-cost way to add reliable sun protection and a cooler outdoor space. Its strongest selling point is the high-density knitted mesh that blocks up to 95% of UV rays while still allowing cooling breezes through, so patios and decks feel shaded without becoming stagnant. For anyone who wants durable sun cover that is straightforward to install and looks good, this sail earns close attention.

Key Features

• High shading rate: The HDPE fabric delivers about 90%-95% shading so it significantly reduces direct sunlight and UV exposure on hot days.
• UV protection: The material is formulated to block 95% of UV rays, helping protect skin and outdoor furnishings from sun damage.
• Permeable mesh: The knitted design lets cooling breezes and light rain pass through, preventing heat buildup under the sail.
• Durable construction: Cut from a complete mesh and finished with double strength stitched seams for longer life at the edges and corners.
• Mounting hardware included: Four anti-rust D-rings and four cords come with the sail to simplify attachment to posts or hooks.
• Curved edge design: The curved edges help prevent sagging for a cleaner look and improved shading performance.

Who It's For

This shade sail is well suited for homeowners with a patio, deck, pergola or backyard seating area who want a visible improvement in comfort without a permanent structure. People who value airflow and UV reduction will appreciate the breathable HDPE mesh and 95% UV blocking performance.

It is not ideal for customers seeking a fully waterproof canopy or exact inch-perfect dimensions; the fabric is permeable to water and the measured length can vary by up to 4 in from the D-ring edges, so custom fitting or professional installation may be needed for complex sites.

Our Verdict

Frequently Asked Questions

Is this shade sail waterproof?
No, the fabric is permeable and allows light rain to pass through; it is designed for sun protection and airflow rather than waterproofing.

How is the size measured?
Length is measured from the outer edge of one D-ring to the outer edge of the opposite D-ring, and a tolerance applies, so allow for 0.5-1 ft at mounting points.

Are mounting accessories included?
The sail includes 4 anti-rust D-rings and 4 cords; heavier-duty hardware or specialty anchors should be purchased separately if needed.
