Custom Size 11ft x 15ft x 18.6ft Right Triangle Sun Shade Sail - UPF50

In this review of the custom right triangle sun shade sail, the bottom line is straightforward: this is a purpose-built shade solution for homeowners and small commercial spaces that need reliable UV protection and a tailored fit. The single biggest reason to buy is its practical combination of 95% UV blockage and customizable D-ring-to-D-ring sizing, which makes it useful where standard sails won't fit. The reviewer found it to be durable in hot weather and effective at cooling shaded areas while offering straightforward installation for anyone willing to measure carefully.

Key Features

• 95% Sun Protection: Blocks up to 95% of harmful UV rays using 200 GSM HDPE fabric to reduce sun exposure for people and pets.
• Temperature Reduction: Lowers ambient temperature by up to 15 degrees in shaded areas to make patios, play areas, or animal runs noticeably cooler.
• Custom Fit: Measured from D-ring to D-ring so the sail can be made to fit irregular or specific spaces instead of forcing a standard size solution.
• Durable Construction: Stainless steel D-rings, reinforced edges, and double-layer stitching add strength and resist fraying for longer life in outdoor conditions.
• Permeable Design: Water and air permeable fabric reduces wind load and prevents water pooling while still providing protection from sun.
• 3 Year Assurance: A manufacturer assurance period that supports confidence in the product's build quality and materials.

Who It's For

This shade sail suits homeowners, small business owners, and hobbyists who need a tailored shade solution for patios, decks, vegetable beds, or animal enclosures and who value high UV protection. Installers who can take careful D-ring-to-D-ring measurements will benefit most because the custom sizing is the main advantage over off-the-shelf sails.

Those who should look elsewhere include buyers seeking a fully rigid canopy or a fully waterproof awning; this sail is water and air permeable and is intended primarily for sun protection and cooling rather than total rain shelter.

Pros & Cons

Pros

• High UV protection that blocks approximately 95% of harmful rays for safer outdoor time.
• Custom D-ring sizing lets the sail fit tricky or nonstandard spaces better than generic sizes.
• Sturdy hardware and reinforced stitching raise confidence in durability and long-term use.
• Permeable fabric reduces wind stress and avoids water pooling during light rain.

Cons

• Customers have noted sizing can feel smaller than expected, so exact measurements are critical to avoid disappointment.
• Not a waterproof structure, so it will not provide full rain protection like a solid-roof awning.

Our Verdict

For anyone who needs a tailored shade solution with strong sun protection, this custom right triangle sail is a sensible buy because it balances high UV blockage, durable construction, and a made-to-measure fit. It offers clear value for patios, pergolas, and animal runs, provided buyers measure carefully and understand it is not a waterproof canopy.

Frequently Asked Questions

How should I measure for a custom sail?
Measure from D-ring to D-ring at each corner and allow recommended gaps at the connection points; precise measurements ensure the custom sail fits as intended.

Will this block rain?
The fabric is water permeable, so it reduces sun and heat but will not act as a full waterproof roof during heavy rain.

Is the sail suitable for windy areas?
The permeable HDPE fabric and reinforced edges reduce wind load, but proper tensioning and solid anchor points are required for windy locations.
