ShadeMart 16 ft x 17 ft Blue Sun Shade Sail UPF50 - Heavy Duty Outdoor

In this review of the ShadeMart 16' x 17' Blue Sun Shade Sail, the bottom line is simple: this is a practical, heavy duty rectangle shade for anyone who needs durable UV protection over a patio, carport, or pool area. The sail is made from woven HDPE fabric with stainless steel D rings and heavy webbing, and its main selling point is effective sun protection and breathability rather than full waterproofing. For buyers who want a large, custom-capable shade that lowers surface temperatures and survives harsh weather, this sail delivers.

Key Features

• MATERIAL: Woven HDPE fabric provides a strong, tear-resistant canopy that stands up to regular outdoor use.
• UV PROTECTION: Blocks up to 95% of harmful UV rays with a UPF50 rating, helping reduce temperatures beneath the sail by around 10 to 15 degrees.
• BREATHABILITY: Water permeable and breathable construction allows rain and air to pass through so pooling and wind load are reduced.
• HARDWARE: Corner D rings are stainless steel and sewn into heavy white webbing for secure mounting points with proper hardware kits.
• CUSTOM SIZE OPTIONS: A range of custom sizes is available so you can match your venue when you measure accurately before ordering.
• STYLING: Rectangle shape and color choices make it a useful decorative element as well as functional shade.

Who It's For

The ShadeMart rectangle sail is best for homeowners and small business owners who need a large, breathable canopy for patios, carports, pergolas, pool areas or market stalls and who value UV protection and durability over full waterproofing. It is also well suited for anyone who wants a customizable-size option and easy-to-install hardware attachments to poles, trees, or walls.

Those who need a fully waterproof solution or require a precisely cut industrial rectangle without any size variance should look elsewhere, since the fabric is water permeable and manual measurements may introduce slight variations in shape despite a constant area of fabric.
