The CORE Foam Roller uses high density EVA foam in an exclusive multi-density GRID® pattern to deliver targeted, moderate compression for a comfortable total body massage. Ideal for anyone new to foam rolling, in need of softer compression, or recovering from an injury, it aids in muscle recovery, improves flexibility, and enhances mobility. This gray, solid-core EVA foam roller is more durable than standard polypropylene rollers that can break down and become soft. It also provides softer, less intense compression than the GRID® Foam Roller. Available in 12", 18", and 36" lengths. 325 lb. weight limit. Includes a 1 year manufacturer's warranty. One (1) solid-core EVA foam roller.
