The Altegra Elite Canopy
Australian tested and certified UPF50+ Excellent fabric is the foundation of an effective portable shade shelter. Enjoy the outdoors with all day sun protection.
100% waterproof PVC-lined Polyester shields from torrential weather. Externally bound seams and hot-tape seam-sealing keeps you and your 3×4.5m gazebo interior dry.
Quality 330GSM PVC-lined Polyester is the choice fabric for our Elite canopy. The balance of foremost protection, pliability, durability, and professional appeal.
Reinforced for longer life and a stronger hold, all frame-to-material wear points are fortified with additional fabric and are held firmly with Velcro. The result is reduced wear and enhanced durability.
Avoid water pooling, a common marquee canopy trait with extended canopy peaks and top quality material. High peaks and durable material retain tension and optimal water runoff.
A strong marquee needs to be united to remain intact in adverse conditions. The Altegra Elite canopy is extensively secured to your portable shelter by easy to use Velcro anchors.
