Sun Shade Sail Triangle 14ft x 20ft x 20ft Brown - UV Block

In this review of the SUNN Y GUARD triangle sun shade sail, the bottom line is simple: it is an affordable, heavy-duty option for anyone who needs reliable UV protection for a patio, deck, or poolside area. The sail is made of high density polyethylene and claims up to 95% UV blockage, which is exactly what the reviewer found most valuable - strong sun protection combined with a breathable fabric that still allows airflow and some cooling. Installation is straightforward for someone comfortable with measuring and anchoring outdoor hardware, and the included ropes are a helpful touch.

Key Features

• UV Protection: Blocks up to 95% of harmful UV rays so shaded areas remain safer for long daytime use.
• Breathable Fabric: High density polyethylene lets air and some water pass through, reducing heat buildup under the sail.
• Durable Construction: Made from 185GSM material without splicing, which contributes to longer life in harsh sun and storm-prone environments.
• Customizable Size: Custom sizing options make it possible to fit unusual patios, pergolas, or carports when standard sizes do not work.
• Included Accessories: Comes with 3 to 4 pieces of thickened rope to get you started and simplify the initial setup.
• Warranty and Support: Made in USA and backed by a 5 year warranty under normal use, with direct customer support for fit or replacement questions.

Who It's For

This sail is a good match for homeowners wanting an economical shade solution for backyards, pools, BBQ areas, or RV awnings who prioritize sun protection and airflow over full rainproof coverage. It suits DIY installers who can measure their mounting points and leave a 0.5 to 1 ft margin for hardware and tensioning.

People who need a fully waterproof canopy, quick pop-up portability, or hands-off installation by professionals may want to look elsewhere; this design is optimized for UV blocking and breathability rather than total water resistance or tool-free setup.
