15ft x 20ft x 25ft Black Right Triangle Sun Shade Sail - 190 GSM UPF50

In this review the 15' x 20' x 25' Black Right Triangle Sun Shade Sail is assessed for homeowners and small commercial spaces that need strong, long-lasting shade. The bottom line: this sail delivers dependable UV protection and durability because it is made from 190 GSM 100% virgin HDPE with a UV stabilized compound, so it resists fading and tearing under prolonged sun exposure. Installers will appreciate the reinforced edges and D-ring corners, while anyone seeking breathable shade will like that the fabric blocks 95% of UV yet lets air and water pass through.

Key Features

• 190 GSM Virgin HDPE: Thick non-recycled fabric offers improved longevity and resists sunlight damage better than recycled alternatives.
• UV Stabilized Compound: Lab-tested for extended sun exposure so the sail is less likely to dry out, fade, or tear over time.
• 95% UV Blockage: Significantly reduces UV sunlight and ambient temperature under the sail for safer outdoor use.
• Breathable Woven Fabric: Allows water and air to pass through to prevent pooling and reduce wind stress on the canopy.
• Reinforced Edges and D-rings: Heavy double-stitched seams and stainless steel D-rings make mounting more secure and more resistant to fraying.
• 3 Year Limited Warranty: Coverage under normal weather and usage provides added confidence for long-term outdoor installations.

Who It's For

This right triangle shade sail is best for patio, poolside, balcony, carport or small commercial outdoor seating areas where a non-rectangular coverage fits the space. It works well for homeowners and small businesses that need reliable UV protection and prefer a breathable fabric that avoids water pooling.

It is less suitable for buyers who need an all-weather waterproof canopy or those without sturdy anchor points; installation requires proper hardware and attachment points, and hardware kits are sold separately.

Pros & Cons

• Blocks 95% of harmful UV while remaining breathable, helping reduce heat under the sail.

Cons

• Installation hardware is required but sold separately, and wrong rope type can lead to failure if not installed per guidance.
• Not waterproof; breathable design allows water through so it will not shelter fully from heavy rain.
