The Sierra Comfort Foam Roller 36'x6' (SC-0315) is a medium density foam roller made from EVA foam. The dimpled and softened exterior provides extra grip on the surface, with more comfort than a high density foam roller. Durable for repetitive, long-term use, and able to withstand the heaviest of weights. Ideal for self-massage, core and balance exercises. The extended 36' length is advantageous when using for back and shoulder massage, vertical spine alignment, and Pilates practice. Enjoy all the health benefits foam rolling has to offer including, but not limited to; improved blood circulation (throughout skin, muscles, fascia, tendons, and ligaments), relief of tightness in muscles, enhanced motion in spine, and less tension through day-to-day activity.
