FFO Name: Sleeping Bag
"Restores a little HP to party. Also saves game. Used outdoors."
Price: 75 / 50
The Tent is the cheapest way to save the game on the go. They restore 30 HP (or a random amount on the WSC/PSX) to each Warrior and give you the option to save. The CABIN and HOUSE are better versions of this item. They can only be used on the world map. They are available for sale only in 2 towns:
In the Japanese version the Tent is called a Sleeping Bag and the Cabin is called a Tent. As far as I know, Tents return in FF4, 5, 6, 7, 8 & 9 and Sleeping Bags return in at least FF6.
