ShadeMart 12ft x 17ft Green Sun Shade Sail UPF50 Rectangle - Cooler

In this review of the ShadeMart 12' x 17' green sun shade sail, the bottom line is simple: this is a practical, heavy duty rectangular canopy for anyone who wants measurable sun protection and cooler outdoor spaces. The sail is made from woven HDPE with stainless steel D rings and heavy webbing, and it blocks up to 95% of harmful UV rays, which is the single biggest reason to buy for patios, carports or poolside areas where heat reduction and sun protection matter.

Key Features

• Material: Woven HDPE fabric provides a durable, fade-resistant surface that breathes and resists tearing for long outdoor life.
• UV Protection: Blocks up to 95% of harmful UV rays, helping lower temperatures by roughly 10 to 15 degrees beneath the canopy.
• Hardware: Stainless steel corner D rings with heavy duty white webbing create secure anchor points for a reliable installation.
• Water Permeability: The fabric is water permeable and breathable so rain and wind can pass through instead of pooling on top.
• Custom Sizes: Available in a range of custom sizes so buyers can match irregular venues, with the caveat to measure carefully before ordering.

Who It's For

This shade sail is well suited for homeowners and renters who need a cost-effective way to cool a patio, carport, pergola or pool area while still allowing airflow. Landscapers and small businesses that want a decorative, functional canopy will also appreciate the variety of colors and the rectangle shape for simple geometric coverage.

It is less appropriate for buyers who need a fully waterproof solution or an exact precision-cut industrial canopy; this style is explicitly not waterproof and sizes may vary slightly due to manual measurement.

Pros & Cons

Pros

• High UV blocking capability reduces heat and sun exposure under the canopy.
• Durable woven HDPE construction and stainless steel D rings offer long-term durability.
• Breathable, water permeable design prevents water pooling and allows airflow.

Cons

• Not waterproof, so it will not keep the area dry during heavy rain.
• Size and exact rectangle shape can vary slightly due to manual measurement, leading to mixed sizing feedback.
