15ft x 17ft x 22.7ft Right Triangle Sun Shade Sail - 95% UV Block

Our review of this custom size right triangle sun shade sail finds it best suited for homeowners and small commercial patios who need substantial sun protection in an irregular space. The biggest reason to buy is its combination of close-to-complete UV blocking and a customizable, measured-to-fit approach that avoids awkward gaps; the sail is made of 200 GSM HDPE and claims up to 95% sun protection, so it provides reliable coverage and cooler shade where an umbrella or awning won't fit.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays for safer outdoor time.
• Temperature reduction: The mesh structure lowers surface temperatures by up to 15 degrees compared with unshaded areas for a noticeably cooler space.
• Custom fit: Measurements taken from D-ring to D-ring let the sail be made to order so corners and edges sit where you need them.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings improve long-term strength under tension.
• Breathable and water permeable: The weave allows air and water through to prevent pooling and reduce wind load on the canopy.
• Flexible installation: Can be mounted to trees, roofs, walls or poles with standard hardware for many installation layouts.

Who It's For

This shade sail is ideal for homeowners with patios, decks or play areas that need a tailored triangular shade solution and for small commercial spaces that require reliable UV protection without a rigid structure. People who value a neat, custom fit and ventilation will appreciate the fabric and reinforced hardware.

It is less suitable for buyers who want a permanent, fully waterproof canopy or those who expect zero maintenance in extremely harsh sun without eventual wear; one user report cited deterioration after extended outdoor exposure, so heavy UV climates may need periodic inspection or replacement over time.

Pros & Cons

Pros

• Excellent UV blocking and measurable temperature reduction for shaded comfort.
• Custom sizing from D-ring to D-ring ensures a cleaner, tailored installation.
• Sturdy build with reinforced edges, double stitching and stainless steel D-rings for reliable tension.
• Permeable fabric prevents water pooling and eases wind pressure on the sail.

Cons

• Durability has mixed reports; heavy sun exposure may reduce lifespan and require replacement after a year or more.
• Not fully waterproof, so it will not keep an area dry during sustained rain.

Frequently Asked Questions

How should I measure for a custom sail?
Measure from D-ring to D-ring for each side and allow the recommended gap at corners; provide precise dimensions to ensure a tailored fit.

Is this fabric waterproof?
No, the HDPE mesh is water and air permeable to prevent pooling, so it will not keep an area completely dry in heavy rain.

How long will it last outdoors?
Longevity varies by climate and exposure; many users report more than a year of service, but heavy UV environments can cause earlier degradation so inspect annually.
