ABSTRACT:
A drag harness comprises two arm loops, each of which has a fixed length and is adapted to receive a separate arm of a wearer, and a gripping loop having a fixed length, joined to the arm loops. Rather than one gripping loop, a pair of gripping loops, each having a fixed length, can be advantageously used. The arm loops are made from a non-abrading material, which may be rope, such as cotton rope or polyester rope. Alternatively, the non-abrading material may be a material, such as strapping, webbing, or rope, which has a surface finish providing the material with a non-abrading characteristic.
