20ft x 20ft x 20ft Triangle Sun Shade Sail - 95% UV Blockage

In this review of the 20' x 20' x 20' triangle sun shade sail, the bottom line is simple: it is for homeowners and outdoor hosts who need heavy-duty sun protection and a cooler outdoor area. The reviewer found the sail's 95% UV blockage and thick 200 GSM HDPE fabric to be the single biggest reason to buy, as it noticeably reduced temperature and provided reliable coverage across patios, play areas, and poolside spots. Installation is straightforward for anyone comfortable measuring and mounting hardware, and the option to customize measurements makes it a practical choice for irregular spaces.

Key Features

• High UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays to protect skin and reduce fading of outdoor furniture.
• Temperature reduction: The shade sail lowers ambient temperatures by up to 15 degrees compared to unshaded areas, improving comfort on hot days.
• Durable construction: Stainless steel D-rings, reinforced edges, and double-layer stitching increase longevity under sun and wind exposure.
• Custom fit: Made to measure from D-ring to D-ring so the sail can be tailored to specific mounting points and preferred edge styles.
• Air and water permeable: The material sheds heat while allowing airflow and some water passage, preventing pooling and reducing wind stress.
• Three-year assurance: A three-year assurance is included, offering added peace of mind for long-term outdoor use.

Who It's For

This shade sail is ideal for homeowners with patios, decks, play areas, or pools who want substantial sun protection without enclosing the space. It works well for people who value durability and a measured installation, especially where fixed mounting points like trees, walls, or poles already exist.

It is less suited to buyers who expect a completely waterproof canopy or those unwilling to take careful measurements; for fully waterproof awnings or instant pop-up shelters, other products may be a better fit.
