Sun Shade Sail 13ft x 20ft x 23.9ft Triangle Turquoise Blue - UV Block

In this review of the triangular sun shade sail, the bottom line is simple: it is a practical, budget-friendly option for anyone who wants reliable sun protection for a yard, patio or pool area. The SUNN Y GUARD sail impressed for its material and UV block performance, making it a solid choice for homeowners and renters who need a low-maintenance canopy. The single biggest reason to buy is the combination of up to 95% UV protection and a breathable weave that keeps covered areas noticeably cooler without trapping heat.

Key Features

• High density material: The 185 GSM high density polyethylene fabric resists tearing and is made without spliced panels for a cleaner, more durable shade surface.
• Strong UV protection: The weave blocks up to 95% of harmful UV rays, reducing sun exposure for people and furnishings beneath the sail.
• Breathable cooling: The fabric allows air and water to pass through, cutting radiant heat while avoiding the trapped-heat feeling of solid canopies.
• Custom sizing available: The brand offers custom sizes to fit awkward or bespoke outdoor layouts, which is helpful when standard sails do not align with anchor points.
• Included installation ropes: The package includes 3 thickened ropes for triangle setups so you can get the sail up quickly, with options to add stainless steel accessories for longer life.
• Versatile placement: The curved triangle works across patios, decks, carports, pool areas and play spaces for many outdoor setups.

Who It's For

This sun shade sail is aimed at homeowners, renters and small facility managers who want an inexpensive, effective shade solution that can be installed with basic hardware and ropes. It is especially useful for those who need a breathable canopy to reduce sun exposure while allowing airflow over patios, BBQ areas, sandbox covers and poolside seating.

People who need permanent, fully waterproof roofing or a motorized retractable awning should look elsewhere; this sail is designed for sun and light rain with a permeable fabric and does not replace solid roofing. Also, those requiring precise, professional-grade mounting hardware will want to add the recommended stainless steel accessories for the best long-term durability.

Frequently Asked Questions

Is this sail waterproof?
Not fully; the breathable HDPE fabric allows water to pass through, so it sheds light rain but will not function as a waterproof roof.

Are mounting accessories included?
The package includes 3 thickened ropes for a triangle sail, but the manufacturer recommends buying stainless steel sunshade accessories for greater durability.

Can I order a custom size?
Yes, SUNN Y GUARD offers custom sizing to fit unique outdoor spaces and asks customers to measure and leave a 0.5-1 ft margin for hardware and rope.
