Custom Size 13ft x 17ft x 21.4ft Red Right Triangle Sun Shade Sail

In this review of the 13' x 17' x 21.4' red right triangle sun shade sail the bottom line is simple: this is a practical, heavy-duty shade solution for patios, play areas, and small commercial spaces that need strong sun protection without a permanent structure. The reviewer found it best for users who want a customized fit and substantial UV defense; its 200 GSM HDPE construction promises 95% sun protection and a cooler area beneath the sail, making it a clear choice when sun blockage and airflow are priorities.

Key Features

• 95% UV blockage: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays to protect people and furniture beneath the sail.
• Temperature reduction: Properly installed, the sail reduces ambient temperatures by as much as 15 degrees compared to unshaded areas, improving comfort on hot days.
• Custom sizing: Measured D-ring to D-ring for a tailored fit, the sail can be ordered to match irregular spaces or adjusted for straighter edges if requested.
• Durable construction: Stainless steel D-rings, reinforced edges and double-layer stitching resist fraying and support longer term use.
• Water and air permeable: The breathable weave sheds some water while allowing airflow, reducing wind stress and pooling during light rain.
• Easy installation: Can be attached to trees, roofs or posts using mounting hardware kits; allow a 0.5 ft gap at corners or reduce distances slightly for tighter fits.

Who It's For

This shade sail is ideal for homeowners, small business operators and landscapers who need a customizable, portable canopy for patios, playgrounds, poolside areas, or outdoor seating. It suits people who value sun protection and airflow over a rigid, waterproof canopy and who can provide sturdy anchor points for installation.

Those who want a fully waterproof awning, an instant pop-up umbrella, or a permanently mounted metal structure should look elsewhere; heavy, continuous downpours and applications needing complete water resistance are not the primary use cases for this breathable HDPE sail.

Pros & Cons

Pros

• High UV protection from the 200 GSM HDPE material keeps shaded areas noticeably cooler.
• Solid build with stainless D-rings and reinforced edges offers better long-term strength than cheaper sails.
• Custom sizing and the option for straight edges make it flexible for unusual spaces.

Cons

• Durability in continuous harsh sun can vary; some users report good multi-year life while others experienced earlier degradation.
• Not fully waterproof, so it is less suitable where complete rain protection is required.

Frequently Asked Questions

Is this sail fully waterproof?
The fabric is water and air permeable, so it sheds light rain but is not designed as a fully waterproof awning.

How should I measure for a custom fit?
Measure from D-ring to D-ring for the precise dimensions you need and allow recommended corner gaps for proper tension.

How long will it last in strong sun?
Construction includes reinforced edges and stainless D-rings with a 3 year assurance, but actual longevity can vary with exposure and installation; some customers report over a year of reliable use while results differ.
