Sun Shade Sail 13ft x 17ft Turquoise Blue Rectangle - UV Block Canopy

In this review of the Sun Shade Sail 13' x 17' Turquoise Blue Rectangle, the bottom line is simple: it suits homeowners and renters who want reliable, wide-area shade without heavy structure work. The sail's main selling point is its high-density polyethylene fabric with a claimed 90%-95% shading rate that blocks up to 95% of UV rays while still allowing cooling breezes and water to pass through. For anyone looking to convert a patio, deck or pergola into a cooler, usable space quickly, this sail is a pragmatic and affordable option.

Key Features

• High shading rate: The fabric provides strong sun protection by blocking up to 95% of UV rays for noticeably cooler, protected outdoor areas.
• Breathable mesh: The knitted mesh lets air flow through so the shaded area stays ventilated rather than trapping heat.
• Durable construction: Cut from a complete mesh and finished with double strength stitched seams to resist fraying and wear.
• Installation hardware included: Four anti-rust D-rings and four cords come with the sail for a straightforward, temporary installation.
• Curved edge design: Curved edges reduce sagging and improve overall tension for a neater appearance and better shade coverage.
• Permeable to rain: The sail allows light rain to pass through so it will not pond or hold water during showers.

Who It's For

This shade sail is ideal for homeowners, renters, and DIYers who need a quick way to add large-area shade to a patio, backyard, deck or pergola without building permanent structures. It works well for areas that benefit from dappled light rather than total blackout, and for people who value UV protection while retaining airflow.

This is not intended for customers who need a fully waterproof canopy or an exact precision-fit item without any size tolerance; the fabric length is measured from D-ring edge to D-ring edge with a tolerance of up to 4 in and the sail is not waterproof. Those seeking a rigid, permanent roof or full rain protection should look at solid canopies instead.

Pros & Cons

Pros

• Effective sun and UV blocking that creates a comfortable shaded area.
• Breathable mesh keeps air moving and avoids heat buildup under the sail.
• Sturdy stitching and anti-rust D-rings contribute to durable outdoor use.
• Curved edges and included cords make installation neater and easier to tension.

Cons

• The sail is permeable and not waterproof, so it will not provide full rain protection.
• Length is measured D-ring to D-ring with a tolerance, so exact fit may vary and accessories are sold separately.
