The wall count on this 10-ft by 20-ft canopy is not fixed at six, it is anything from 0 to 6. Run it fully open as a shade roof, add two panels against a crosswind, take it to three or four as the sun moves, or close all six for a fully enclosed space, and the two zippered panels can also simply be rolled up rather than removed when access is all that is wanted. That range of configurations is the reason a single canopy covers a whole season of different days. Two of the six carry double-sided zippers for access from either direction and two carry transparent windows that let natural light in when the walls are closed. Setup is a one-hand center lock system, fast and effortless and entirely tool-free, and pinch-free buttons make height adjustment easy and safe across 3 levels of 8.2-ft, 8.5-ft and 8.8-ft, giving 5.2-ft, 5.5-ft or 5.8-ft of ground clearance. Support comes from a heavy-duty carbon steel frame, and the anchoring set is one of the most complete in its class with 6 sandbags, 10 ground stakes and 6 wind ropes adding stability at each corner. Thick Oxford cloth with a silver coating gives UPF50+ sun protection and drizzle resistance overhead. The 65-lb canopy stores in a wheeled bag measuring 47-in by 15-in by 10.5-in, and it is ideal for BBQs, camping, tailgates, markets and picnics.
