The Marmot Limestone Lanai Screen Room lets us enjoy some bug-free fun at the campsite, the beach, or our backyard. This sceened-in canopy shelter sets up easily and has three zippered doors, so hikers, swimmers, family members, and potluckers can come and go as they please. With 7 feet of clearance and more than 100 square feet of floor space, the Limestone Lanai Screen Room is big enough to fit over a picnic table and provides much-needed sun and bug protection for our summer gatherings outdoors.
