The TriggerPoint Eco GRID, the original hollow core foam roller, is now eco-friendly with 30% renewable, biobased materials, in addition to EVA foam and a recycled plastic core. Featuring a patented multi-density foam surface, the Eco GRID delivers firm compression while channeling blood and oxygen needed to repair muscles. Proprietary Distrodensity® zones replicate the feeling of a massage therapist’s hands, helping to relieve tight muscles and enhance recovery.
