What is another word for lean-to tent?
Pronunciation: [lˈiːn tuː tˈɛnt] (IPA) 
A lean-to tent can be known by several other names such as a bivouac tent, fly shelter, tarp shelter, or improvised shelter. The terms 'bivouac' and 'bivy' are sometimes used interchangeably with a lean-to tent, particularly in mountain and camping circles. In survival situations, people often fashion a so-called 'emergency shelter' or 'improvised shelter' using whatever resources they can find on hand.

No matter what term is used, a lean-to tent usually describes a shelter that is simple to construct, yet useful in a variety of situations.
