This 10 lb sandbag is designed with the yoga practitioner in mind. It will sit easily over your diaphragm to strengthen breathing, and it will nestle in at your pelvis to create grounding and lower back and hip release. The length is perfect for laying on front of thighs, or to rest on your hands during savasana. With both both an inner and outer cover, this sandbag is washable. The fill is hypoallergenic sand that is specifically created for kids' sandboxes.
