ShadeMart 11ft x 20ft Turquoise Rectangle Sun Shade Sail - UPF50

Our review of the ShadeMart 11' x 20' Turquoise Rectangle Sun Shade Sail finds it best suited for homeowners and DIY installers who want durable, breathable sun protection over a patio, carport, or pool area. The single biggest reason to buy is reliable daytime cooling and UV blockage: the woven HDPE fabric is rated to block up to 95% of harmful rays and noticeably lowers temperature beneath the canopy. The review highlights practical details like stainless steel corner D rings and heavy duty webbing that make this sail both usable and long lasting in typical outdoor settings.

Key Features

• MATERIAL: Woven HDPE fabric provides strong, tear-resistant coverage while remaining lightweight for easier handling and installation.
• UV PROTECTION: Blocks up to 95% of harmful UV rays, offering substantial sun protection and helping lower surface temperatures beneath the sail.
• BREATHABILITY: The water permeable, breathable weave allows rain and air to pass through so water will not pool and wind loads are reduced.
• HARDWARE: Stainless steel corner D rings attached to heavy duty white webbing provide secure attachment points for common hardware kits.
• CUSTOM SIZE OPTIONS: Available in multiple sizes and custom dimensions so the sail can be matched to patios, pergolas, or carports when measurements are accurate.
• STYLING: Rectangle shape and bold turquoise color act as both functional shade and a decorative element to update an outdoor area.

Who It's For

This shade sail is ideal for homeowners, renters with permission to anchor to posts or walls, and DIYers who want a cost-effective, UV-blocking canopy for a pergola, patio, poolside area, or carport. It suits people who prefer a breathable, water-permeable fabric that reduces heat rather than trapping moisture.

It is not for someone who needs a fully waterproof roof or a rigid permanent structure; if you require complete waterproofing, a dedicated waterproof canopy or solid roofing solution would be a better choice.

Pros & Cons

Pros

• High UPF performance and real heat reduction keep outdoor seating areas more comfortable.
• Durable construction with stainless steel D rings and heavy duty webbing for secure mounting.
• Breathable, water permeable design prevents pooling and reduces wind stress on anchors.
• Custom sizing and multiple colors let you tailor the sail to a specific outdoor layout and style.

Cons

• Not waterproof, so it will not provide full rain protection or act as a rainproof roof.
• Some buyers report size or shape variations due to manual measurement, so careful measuring is required.

Our Verdict

Its durable HDPE construction and stainless steel D rings make it well suited to patios, pools, and carports where breathability and UV resistance are priorities; choose a different product only if you need a waterproof covering.
