Custom Size 11ft x 15ft x 18.6ft Blue Right Triangle Sun Shade Sail

Our review of this custom size blue right triangle sun shade sail finds it best for homeowners and small commercial spaces that need reliable sun protection and a tailored fit. The single biggest reason to buy is its strong combination of 95% UV protection and customizable D-ring-to-D-ring sizing, which makes it easy to cover awkward patios or play areas where standard sails fall short. Installation is straightforward for anyone comfortable with basic mounting hardware, and the fabric and reinforced stitching signal a product built to perform as a long-term shade solution.

Key Features

• 95% Sun Protection: The 200 GSM HDPE fabric blocks up to 95% of UV rays, lowering sun exposure for people and furniture beneath the sail.
• Temperature Reduction: The mesh material reduces surface temperatures by as much as 15 degrees compared to unshaded areas, making outdoor spaces noticeably cooler.
• Custom Fit: The sail is made to order using D-ring to D-ring measurements so it can match irregular layouts and avoid awkward gaps.
• Durable Construction: Stainless steel D-rings, reinforced edges, and double-layer stitching improve strength and resistance to fraying in normal outdoor use.
• Easy Installation: The flexible design allows attachment to trees, walls, roofs, or poles using standard mounting kits with guidance on recommended corner gaps.
• Commercial Standard: The build meets commercial-grade expectations, suitable for patios, play areas, and light commercial shade applications.

Who It's For

This shade sail is ideal for homeowners, small business owners and landscape professionals who need a non-permanent, tailored shading solution for patios, poolsides, playgrounds, or outdoor seating areas. The custom sizing option is especially valuable when standard rectangular or square sails do not fit the available mounting points or when a precise aesthetic is required.

It may be less suitable for buyers who expect a fully waterproof canopy or those who need constant heavy-duty storm protection; the fabric is water and air permeable and intended for sun protection and cooling rather than complete weatherproofing.

Pros & Cons

Pros

• Excellent UV protection with up to 95% blockage for safer outdoor time.
• Measurable cooling effect, reducing temperatures up to 15 degrees under the sail.
• Robust hardware and reinforced stitching improve longevity and resistance to wear.
• Custom D-ring sizing allows a precise fit in irregular spaces.

Cons

• Not fully waterproof; designed to be water and air permeable rather than a rainproof canopy.
• Some users report mixed long-term durability in very harsh sun exposure, so lifespan can vary by climate and care.

Frequently Asked Questions

Is the sail waterproof?
The fabric is water and air permeable, so it sheds some water but is not intended as a fully waterproof canopy.

How should I measure for a custom sail?
Measure from D-ring to D-ring at each corner; the sail is made to those exact distances for the best fit.

How durable is the material in strong sun?
The 200 GSM HDPE with reinforced edges and stainless hardware is built for longevity, but extreme, continuous sun exposure can shorten service life in some climates.
