A restraint is described that may be constructed as a harness. A generally tube-shaped sleeve having a main portion has at least one hole formed therein. At least one flap extends from a first side of the main portion and attaches to a second side of the main portion. The at least one flap completes a hole that receives a leg of a wearer of the restraint. A pair of drawstrings is provided wherein each drawstring is attached to a different side of the main portion. Each drawstring can be configured to be coupled together, typically using a latching mechanism. The drawstrings adjust the fit of the restraint to the girth of the wearer of the restraint. A loop on the main portion of the harness permits fastening of a leash to the restraint.
