Flexible garden hoses, or retractable garden hoses, are very flexible, so they don't kink as much. The flexible hose expands when water runs through it and shrinks back to its original compact size after use. This makes it much lighter than the traditional garden hose. And it doesn't take up a lot of space when you store it in your shed. Flexible garden hoses come in various lengths. There are flexible garden hoses of 30m, 20m, and 15m, for example.
