A flexible material includes a plurality of separate resilient elements joined to a flexible, resiliently stretchable substrate. Such a material is suitable for providing protective war for human and animal bodies. Preferably, the elements includes a foam material such as a closed cell polyethylene foam and the substrate includes a knitted fabric. In an advantageous embodiment, a second flexible substrate is bonded over the elements to sandwich them between the two layers of substrate.
