ShadeMart 14ft x 17ft Green Sun Shade Sail UPF50 Rectangle - Cool

Our review of the ShadeMart 14' x 17' Green Sun Shade Sail finds it best for homeowners and small-business owners who need a durable, breathable sun cover that meaningfully cuts heat without trapping moisture. The sail's woven HDPE fabric and stainless steel D rings feel built for outdoor use, and the UPF50 blocking of sunlight delivers noticeably cooler shade. It is not waterproof, which is an intentional tradeoff for airflow and rain permeability, so buyers should choose it where water drainage and breathability are priorities.

Key Features

• Material: Woven HDPE fabric provides a tough, tear-resistant surface that stands up to regular outdoor exposure.
• UV protection: UPF50-rated fabric blocks up to 95% of harmful UV rays, helping lower temperatures under the sail by roughly 10 to 15 degrees.
• Breathability: The water-permeable weave allows rain and air to pass through so puddling and wind strain are greatly reduced.
• Hardware: Stainless steel corner D rings attached to heavy duty white webbing make for secure anchoring to poles, walls, or trees.
• Custom sizing: Multiple custom size options are available so you can order a sail to better fit patios, carports, pools, or pergolas.

Who It's For

This shade sail suits homeowners, renters with outdoor patios, and operators of small outdoor businesses who want reliable sun protection that reduces heat and UV exposure while maintaining airflow. It is especially useful where occasional rain should pass through the fabric rather than collect on a waterproof canopy.

Those who need a fully waterproof cover, exacting rectilinear precision for architectural installations, or load-bearing roofing should look elsewhere. Also, buyers who cannot measure their installation area accurately should be cautious since custom sizes require careful measurement and sails may vary slightly due to manual cutting.

Pros & Cons

Pros

• Durable HDPE weave and stainless steel D rings deliver long-term outdoor resilience and secure mounting.
• High sun protection with UPF50 blocking, noticeably reducing heat beneath the sail.
• Breathable, water-permeable design prevents pooling and reduces wind strain on the fabric.

Cons

• Not waterproof, so it will not keep the area completely dry during rain.
• Size and shape can vary slightly from expectations; accurate measuring is necessary and some buyers reported non-perfect rectangles.
