Custom Size 17ft x 23ft x 28.6ft Right Triangle Sun Shade Sail - UPF50

In this review the Custom Size 17' x 23' x 28.6' Right Triangle Sun Shade Sail is examined for homeowners and small commercial users who need heavy-duty sun protection in awkward spaces. The bottom line: this shade sail delivers serious sun blockage and cooler shade because it is made from 200 GSM HDPE that blocks up to 95% of UV, and its reinforced hardware and stitching give it a commercial-standard feel. It is best for those who want a custom-fit triangle sail that reduces temperature and holds up to summer conditions, though exact sizing must be measured from D-ring to D-ring.

Key Features

• 95% UV blockage: The 200 GSM HDPE fabric blocks up to 95% of harmful rays so shaded areas stay safer for people, pets, and plants.
• Temperature reduction: The sail can lower ambient temperature by up to 15 degrees compared to unshaded areas, making outdoor spaces noticeably cooler.
• Commercial-grade durability: Reinforced edges, double-layer stitching, and stainless steel D-rings resist fraying and deliver longer service life.
• Custom sizing: Measurements are taken D-ring to D-ring so the sail can be made to fit nonstandard or tight triangular layouts.
• Air and water permeable: The woven HDPE lets air and water pass through, reducing wind load and preventing pooling.
• Flexible installation: It can be anchored to trees, roofs, walls, or poles and includes guidance on corner gap allowances for best tensioning.

Who It's For

The sail is ideal for homeowners with patios, poolside areas, chicken coops, or commercial outdoor seating that need reliable UV protection and cooler shade without a fixed pergola. It suits buyers who can measure precisely from D-ring to D-ring and want a tailored triangle sail rather than an off-the-shelf rectangle.

Customers who prefer rigid, weatherproof awnings or who need fully waterproof canopies should look elsewhere, since this product is designed to be water and air permeable rather than a waterproof shelter.

Pros & Cons

Pros

• High sun protection from the 95% UV blockage fabric delivers safer shaded areas.
• Commercial-standard hardware and double stitching add long-term durability and value.
• The custom-fit approach lets the sail work in irregular triangle spaces where standard sizes fail.
• Air and water permeability reduces wind stress and prevents water pooling on the fabric.

Cons

• Precise measuring is required; some customers report the delivered size feels smaller than expected when corners are counted.
• Not fully waterproof, so it will not keep heavy rain completely out.

Specifications

Our Verdict

The Custom Size 17' x 23' x 28.6' right triangle shade sail is a solid choice for anyone needing heavy UV protection and cooler outdoor space with a tailored fit. Its durable 200 GSM HDPE, reinforced hardware, and permeability make it practical for patios, yards, and light commercial use; just measure carefully since perceived size can be smaller if corner gaps are not accounted for.

Is this sail waterproof?
Answer. No, it is water permeable by design to prevent pooling and reduce wind load; it will not be fully waterproof in heavy rain.

How should I measure for a custom sail?
Answer. Measure from D-ring to D-ring for each corner and allow at least 0.5 ft gap between D-rings and poles, or reduce by 1 to 1.5 ft per side where needed for tension.

How durable is the fabric and hardware?
Answer. The 200 GSM HDPE fabric with double-layer stitching and stainless steel D-rings is marketed as commercial standard and comes with a 3-year assurance for added confidence.
