Tow floats for swimrun are primarily a safety aid. They are increasingly popular amongst individual participants to provide visibility in the water. Tow floats are often used anyway by open water swimmers and come in a range of shapes, colours and sizes. Then there are also safety aids, self inflating floats with gas canisters. For those who practice swimrun is a hobby, there are an increasing number of wild swim bags with the RuckRaft perhaps one of the most famous for swimrun adventures.
