ShadeMart 12ft x 17ft Turquoise Rectangle Sun Shade Sail - UPF50

In this review of the ShadeMart 12' x 17' Turquoise Rectangle Sun Shade Sail, the verdict is straightforward: this is a practical, heavy duty shade for homeowners and small businesses who want reliable sun protection and airflow without a solid roof. The sail's woven HDPE fabric and stainless steel corner D rings give it durability, while the water permeable design and UPF50 shading make it effective at lowering temperatures and protecting skin and outdoor furniture. It is best for patios, carports, pools and yard areas where breathability and UV blocking matter more than full waterproofing.

Key Features

• Woven HDPE fabric: Provides a tough, tear-resistant canopy that holds up under sun exposure and is designed for long-term outdoor use.
• Stainless steel D rings: Corner rings attached to heavy duty white webbing make mounting secure and reduce corrosion risk in outdoor conditions.
• Water permeable design: Allows rain and air to pass through so water does not pool and the shaded area stays well ventilated.
• UPF50 sun protection: Blocks up to 95% of harmful UV rays, which significantly lowers temperatures beneath the sail for more comfortable outdoor use.
• Custom sizing available: Multiple sizes and custom orders allow buyers to match odd layouts and larger venues when precise coverage is needed.
• Decorative rectangle shape: A simple rectangular profile integrates easily with patios, pergolas and carports while adding color and visual interest.

Who It's For

The ShadeMart rectangle sun sail is aimed at homeowners and small property managers who need a durable, breathable shade for patios, pool areas, carports and yards. It works well where airflow and UV protection are priorities and where buyers prefer a fabric solution that drains rather than a rigid, waterproof roof.

It is less appropriate for buyers who need a fully waterproof cover or exact factory-cut architectural symmetry; customers should measure carefully because manual measurements and fabric cutting can produce slight variations in shape even when the covered area remains consistent.

Pros & Cons

Pros

• High density polyethylene weave and stainless steel hardware deliver noticeable durability and corrosion resistance for outdoor use.
• Effective UPF50 shading reduces heat beneath the sail and protects people and furnishings from sun damage.
• Breathable, water permeable fabric prevents pooling and promotes airflow, improving comfort on hot days.
• Available in custom sizes, making it flexible for irregular spaces and larger coverage needs.

Cons

• Not waterproof, so it will not keep an area dry during steady rain.
• Some customers report variance in shape and size perception, so careful measuring and realistic expectations are required.
