Custom Size 15ft x 16ft x 21.9ft Right Triangle Sun Shade Sail - UPF50

Our review of this custom size right triangle sun shade sail finds it well suited for homeowners and small businesses who need tailored sun protection with solid build quality. Measured D-ring to D-ring for a precise fit, this shade sail's standout attribute is its 95% UV protection delivered by 200 GSM HDPE fabric, which cuts temperatures in shaded areas by up to about 15 degrees. Installation is straightforward for anyone comfortable with basic hardware, and the reinforced edges and stainless steel D-rings promise a long service life in most outdoor conditions.

Key Features

• 95% Sun Protection: The 200 GSM HDPE fabric blocks up to 95% of UV rays to reduce sun exposure and protect people and furniture underneath.
• Temperature Reduction: The shade sail lowers ambient temperature in covered areas by up to 15 degrees, improving comfort for patios and play areas.
• Custom Fit: Made to order by D-ring to D-ring measurements so the sail fits irregular or exact spaces better than off-the-shelf sizes.
• Durable Construction: Reinforced edges, double-layer stitching and stainless steel D-rings increase resistance to tearing and wear in outdoor conditions.
• Easy Installation: Can be mounted to trees, walls, roofs or poles using standard mounting kits and allows corner gap adjustments for tensioning.
• Breathable and Draining: The water and air permeable weave reduces wind pressure and prevents water pooling during light rain.

Who It's For

This shade sail is ideal for homeowners with a specific irregular area to cover, small cafes or poolside settings that want reliable UV protection without bulky structures, and anyone who values a custom-fit solution for patios, playgrounds, or decks. Buyers who plan to attach the sail to trees, walls, or existing posts will appreciate the flexible mounting options.

It is less suitable for customers who want a hard waterproof canopy or a structure meant to withstand constant heavy storms; the fabric is water permeable and best for sun protection and light rain, not full waterproofing or hurricane-level wind loads.

Pros & Cons

Frequently Asked Questions

Is this shade sail waterproof?
It is water and air permeable, so it sheds light rain by allowing water to pass through rather than pooling but is not a fully waterproof canopy.

How should I measure for a custom fit?
Provide D-ring to D-ring measurements for each corner so the sail is made to the exact space; leave the recommended corner gap for tensioning when installing.

How long will it last outside?
Durability is generally good with reinforced edges and stainless D-rings, and many users report over a year of use, but results vary with sun exposure and local climate.
