Removable sidewalls turn this dome from an open shade canopy into an enclosed room in a few minutes. All 4 zip off, and with mesh doors and 2 roof vents in play the interior can be opened for breeze or closed for privacy at a campsite. The span measures 13.3 ft on each side with 7.6 ft of headroom, shading a group of 12 to 15 through a long beach afternoon or a shared campsite meal. Silver-coated oxford cloth resists tearing and carries a UPF 50+ rating, with enough water repellency for a passing shower rather than sustained rain. A reinforced frame on fiberglass poles takes the load, and 12 ground stakes, 4 wind ropes and 4 ankle straps pin it down. The 9.5 ft mesh door swings wide for coolers and chairs; packed weight is 23 lbs.
