ShadeMart 11 ft x 13 ft Green Sun Shade Sail UPF50 Rectangle

In this review of the ShadeMart 11' x 13' green sun shade sail, the bottom line is clear: this rectangle canopy is best for homeowners or renters who want a durable, breathable solution to cut sun and heat for patios, carports, and poolside areas. The single biggest reason to buy is the fabric's combination of woven HDPE construction and UPF50 sun protection, which keeps spaces noticeably cooler while remaining water permeable and long lasting. Installation is straightforward with proper hardware, and the sail doubles as a neat design element for outdoor spaces.

Key Features

• Woven HDPE material: provides durable, tear-resistant fabric that blocks up to 95% of harmful UV rays while remaining breathable for airflow.
• Stainless steel corner D rings: attached to heavy duty webbing for secure anchoring and long-term corrosion resistance in outdoor conditions.
• Water permeable design: allows rain and air to pass through so water does not pool on the sail and it dries quickly after showers.
• Temperature reduction: the fabric significantly lowers temperatures beneath the canopy, improving comfort on hot days.
• Custom sizing available: a range of custom sizes can be ordered so the sail fits unique patios, carports, and pergolas when measured accurately.
• Versatile mounting: with the right hardware kit the sail can be attached to poles, trees, walls, or roofs for many outdoor applications.

Who It's For

This shade sail is ideal for people wanting a practical, low-maintenance sun solution: homeowners who want to cool a patio or pool area, carport owners seeking UV protection, or gardeners who need partial shade for outdoor seating. It suits anyone who prefers breathable fabric that does not trap water and can withstand regular outdoor use.

Those who need a fully waterproof canopy or a perfectly precise rectangle cut to the millimeter should look elsewhere; the product is water permeable by design and may show slight measurement variation from manual cutting, though the fabric area remains constant.

Pros & Cons

Pros

• High UV protection with UPF50-rated woven HDPE that noticeably reduces heat.
