Abstract
A golf putting mat provides a pair of parallel raised portions separated for defining a putting stoke path. Each of the raised portions are constructed as a tubular sleeve with a rigid insert. Each of the sleeves accept two inserts arranged colinearly. The inserts are removable for folding the mat for compact portability. The mat provides a top layer of a golf green simulating material, a bottom layer providing support and non-slip characteristics and a middle layer for preventing the mat from being stretched out of shape when standing upon it.

- a marking on the top surface, the marking providing;
- first, a line laying parallel to the raised portions and bisecting the elongate top surface area, and, second, an indicator for guiding the repeated consistent common placement of the golf ball onto the top surface;
- each of the raised portions comprise a tubular outer shell formed as an extension of the top surface and protruding therefrom, each of the outer shells comprising two joined and colinear shell portions, each of the shell portions enclosing a rod fitted snugly within the each of the shell portions, the rods being removable from the shell portions for enabling the mat to lie folded for compact storage.
