High-End Outdoor Shade System for Patios, Decks & Pools
The Shademaker Solaris 11.5' Octagon Sidepost Umbrella will elevate your outdoor lounging experience with its sleek curves and gentle edges. Drawing inspiration from the larger Polaris model, the Solaris stands out with its easy-to-use crank system and infinite tilt function. It rotates 360° with 8 locking positions so that you can enjoy optimal shade coverage throughout the day.
It's built from commercial-grade fasteners, aluminum hubs and fittings, and a galvanized steel stem to withstand the test of time. Solaris is made from 100% solution-dyed acrylic and polyester fabric, woven by two of the most popular names in outdoor fabrics: Sunbrella® and O'Bravia®. These premium materials offer superior resistance to corrosion, mildew, fading, wear, and tear, making this umbrella perfect for any commercial, market, or residential space.
Also available in 9' Square, 10' Square, 10' Octagon, and LX 10' Square models.
