Sun Shade Sail Triangle 20ft x 24ft x 31.2ft - Breathable UV Block

In this review of the SUNN Y GUARD sun shade sail, the bottom line is simple: this is a practical, budget-friendly shade for homeowners who want reliable UV protection without a permanent structure. The 100% high density polyethylene fabric blocks up to 95% of harmful UV rays while remaining breathable, so it keeps covered areas noticeably cooler. Installation is straightforward for anyone comfortable with basic hardware, and the option for custom sizes and a five year warranty make it especially attractive for patios, poolsides, and backyard seating areas.

Key Features

• UV protection: The fabric blocks up to 95% of harmful UV rays, reducing sun exposure for people and outdoor furniture beneath the sail.
• Breathable material: High density polyethylene lets air and water pass through, which helps keep the shaded area cooler on hot days and prevents water pooling.
• Durable construction: Reinforced edges and solid stitching provide sturdiness that customers say stands up to storms and long summers.
• Customizable size: The brand offers custom sizing to fit irregular spaces and larger outdoor layouts, avoiding awkward gaps or excess fabric.
• Included accessories: Each sail ships with 3 or 4 pieces of rope depending on shape, enough to get started and position the sail for a clean install.
• Warranty and support: Made in USA with a five year warranty under normal use, and customer support is available for sizing or installation questions.

Who It's For

This shade sail is a good choice for homeowners, renters, and facility managers who need a flexible, semi-permanent sunshade for a patio, deck, garden, pool area, or carport. It works well for those who prefer a contemporary look over bulky awnings and who want a solution that breathes so the space stays comfortable.

Those who should look elsewhere include people seeking a completely waterproof canopy or a motorized retractable system; this breathable fabric allows water through and is intended primarily for sun and heat reduction rather than full stormproof coverage.
