Abstract: A brace for supporting a user's lower back and hips has a front belt portion and an enlarged rear portion with a molded depression formed inside. A packet has a plurality of separately sealed liquid chambers interconnected to each other by at least one channel for allowing flow of liquid therebetween whereby equal pressure is applied to the user's lower back and hips wherever there is contact with the packet. This packet is attachable to and detachable from the molded depression so that the liquid may be replaced or cleaned by removing the plug before the packet is refilled with fresh liquid.
