ShadeMart 6 ft x 21 ft Turquoise Rectangle Sun Shade Sail - Breathable

Our review of the ShadeMart 6' x 21' Turquoise Sun Shade Sail finds it best for homeowners and small businesses who need a durable, breathable sun canopy that reduces heat without trapping water. The biggest reason to buy is its combination of woven HDPE fabric and reinforced stainless steel D rings, which together deliver long-lasting shade, easy mounting and a measurable temperature drop in covered areas. It suits patios, carports, pools and equipment covers where airflow and UV protection matter more than full waterproofing.

Key Features

• Material: Woven HDPE fabric provides a sturdy, tear-resistant surface that blocks up to 95% of harmful UV rays while remaining breathable.
• Corner Hardware: Stainless steel D rings attached to heavy duty white webbing give secure anchor points for standard shade hardware kits.
• Breathable Design: The sail is water permeable and allows air to pass through, reducing trapped heat and preventing ponding after rain.
• Temperature Reduction: The fabric lowers temperatures beneath the canopy by roughly 10 to 15 degrees, making outdoor spaces noticeably more comfortable.
• Custom Sizes: Multiple sizes and custom options are available so buyers can match the sail to patios, pergolas, carports or poolside areas.
• Styling: Rectangle shape and turquoise color provide a decorative element that integrates with outdoor designs while delivering shade.

Who It's For

The ShadeMart rectangle sail is ideal for homeowners, renters with permission to anchor to structures, and small business owners wanting an affordable shade solution for patios, carports or pool equipment. Its breathable weave and strong corner fittings suit applications where airflow is important and ponding must be avoided.

People who need a completely waterproof canopy or who cannot install mounting points should look elsewhere; this style is specifically not waterproof and relies on proper anchoring and slope to shed water effectively.

Pros & Cons

Pros

• Durable woven HDPE material delivers strong UV protection and resists tearing in typical outdoor use.
• Stainless steel D rings and heavy webbing make installation secure with common hardware kits.
• Breathable, water-permeable design prevents water pooling and promotes airflow under the canopy.
