PLEASE CAREFULLY WATCH THE DEMO VIDEOS ON THE SANSBUG WEBSITE BEFORE FOLDING IT - the poles will splinter if incorrectly folded! * If the manual that came with the tent contains instructions on how to 4-fold it, then your tent can be packed smaller to a 20 inch disc. Do not attempt to 4-fold your tent if the manual does not have those instructions. Please note that the elastic strap cannot restrain the 4-folded tent; you will need a cinch strap. * Weighs only 2.5 lbs! Folds into a thin disc, only about 1 inch thick. We recommend tri-folding it unless you really need to fit it in your luggage. Many customers have taken the 26 inch disc as carry-on; the thin circular disc is not your regular carry-on shape but it is very light. No one has been turned back yet at the gate.... but if you call the airlines asking if you can take a 26 inch disc, then of course you wil be told that you can"t. * Can be used on top of a cot, bunk bed or air mattress; Length: 86 inches, Width: 39 inches, Height: 35 inches. * Tough polyethylene flooring; 100% polyester mesh (~1200 holes per inch will also protect against no-see-ums); Fiberglass poles.
