CanDo Black Composite High-Density Foam Rollers for Muscle Restoration Massage Therapy Sport Recovery and Physical Therapy 6″ x 36″ Half-Round

36″ half roller. I like to use this roller for the spine laying on my back lengthwise. You can lay on either the rounded/flat side. It is a great way to open the chest. For greater stretch use the 36″x 6″ roller.
