In this review of the 13' x 20' x 23.9' White Right Triangle Sun Shade Sail, the bottom line is simple: this is a practical, heavy-duty shade solution for anyone who needs large, reliable UV protection over a pool, patio, carport or garden. The reviewer found the sail's measured corner-to-corner sizing and slightly curved edges deliver a taut, neat look that resists sagging, while the virgin polyethylene fabric offers strong tensile strength and up to 95% UV blockage for cooler, more comfortable outdoor spaces.
Key Features
- Corner-to-corner measurement: Size is taken from corner to corner so you get the intended coverage and can plan anchor points precisely.
- Curved edge design: Slightly curved edges are calculated to prevent sagging in the middle for a neater, longer-lasting canopy tension.
- Virgin polyethylene fabric: Lightweight with high tensile strength, the fabric balances durability and ease of handling when installing or removing.
- High UV and visibility blockage: Blocks up to 95% of UV and about 90% of visibility to reduce heat and glare underneath the sail.
- Seasonal versatility: Provides cooling and ventilation in summer, some frost protection at night, and slight rain resistance during wet periods.
- Custom orders and warranty: Available for customization and backed by a 3-Year Limited Warranty for added peace of mind.
Who It's For
This shade sail suits homeowners and renters who need broad, reliable sun protection for outdoor living areas such as backyard patios, swimming pools, driveways and carports. It is particularly useful when a flexible, removable canopy is preferred over a permanent structure, and for users who want strong UV protection without blocking airflow.
People who need an exact bespoke fit or complete waterproofing year-round should look elsewhere: while the sail is slightly rainproof and ventilated, it is not a fully waterproof awning replacement. Also, those who prefer very rigid, frame-mounted shade systems may prefer a different product.
Pros & Cons
Pros
- High UV protection keeps shaded areas markedly cooler and more comfortable.
- Curved edge design and corner-to-corner sizing improve tension and reduce sag over time.

Cons
- Hardware inclusion received mixed feedback, so buyers may need to source or upgrade fittings for some installations.
- Only slightly rainproof; not a replacement for fully waterproof or framed awnings.
