 and their smooth exterior facilitates pulling them past trees, posts and other obstacles. Garden hoses are also generally tough enough to survive scraping on rocks and being stepped on without damage or leaking. Most garden hoses are not rated for use with hot water, and their packaging will generally specify whether or not this is the case.
