Sun Shade Sail 13ft x 17ft Terra Red Rectangle Canopy - Cool UV Block

In this review of the 13' x 17' terra red rectangle sun shade sail, the bottom line is simple: it is a cost-effective way to add large-area dappled shade to a patio, deck, or pergola while still allowing airflow. The reviewer found the sail best for homeowners who want reliable UV reduction and a tidy installation without heavy structures; the product's 90%-95% shading performance (80%-85% for the white series) and knitted high-density polyethylene fabric are the main reasons to consider it.

Key Features

• High shading rate: The fabric blocks up to 95% of harmful UV rays, providing substantial sun protection for outdoor seating and play areas.
• Breathable mesh: The knitted high-density polyethylene lets cooling breezes through and allows raindrops to penetrate rather than pool on the surface.
• Durable construction: Cut from a complete mesh with double-strength stitched seams and anti-rust D-rings for long-lasting use in outdoor conditions.
• Curved edge design: The sail's curved edges resist sagging and improve tension, which helps maintain a neat appearance and better shading coverage.
• Included installation cords: Four cords are supplied and four anti-rust D-rings are sewn at the corners to simplify setup and anchoring.

Who It's For

This shade sail is aimed at homeowners and renters who want an affordable, flexible sunshade solution for patios, decks, pergolas, or play areas. It works well for people who prefer a semi-permeable cover that reduces UV exposure while keeping airflow and natural light.

Those who need a completely waterproof canopy, a rigid structure, or a preassembled frame should look elsewhere; this product is a fabric sail that requires separate mounting hardware and some care in spacing and tensioning for best performance.

Pros & Cons

Pros

• High UV blocking and shading rate provides noticeably cooler, protected outdoor space.
• Permeable mesh avoids water pooling and allows breezes, reducing wind load on the fabric.
• Stitched seams and anti-rust D-rings add durability for repeated seasonal use.
• Curved edges reduce sagging and keep the sail taut and attractive once installed.

Cons

• Not waterproof, so it does not provide full rain protection for furniture beneath.
• Mounting hardware is sold separately, and length tolerance requires careful measurement before purchase.

Frequently Asked Questions

Is this shade sail waterproof?
Answer. No, the fabric is permeable and allows raindrops through; it is designed for sun and UV protection rather than full rain cover.

Are mounting accessories included?
Answer. The sail includes 4 cords and D-rings, but additional mounting hardware or hooks should be purchased separately and a 0.5-1 ft clearance is recommended for attachment points.

How precise are the dimensions?
Answer. Lengths are measured from outer edge of D-ring to outer edge of other D-ring and there is a fabric tolerance of up to 4 in, so measure mounting points carefully before ordering.
