get a hessian bag or fertiliser bag . turn it inside out 1/2 way and place a rope through the top 2 cnrs. place over your shoulder and adjust the length of rope to suit the water depth you fish in as wet hessian keeps the fish cool. Used this sort for many years chasing y/fin top of the gulf. for the guys that can not get a hessian bag is try a laptop satchel over the shoulder.
