These polyethelene white non-cross-linked shield blanks are 2 inch thick 2.2lb foam and perfect for creating either strap or punch shields. They are firm, rigid, very light, will last for years, and require no additional padding. These are foam blanks only, and you will have to provide your own straps, handle, and cover.
The Tough versions of the shield are constructed entirely from 4# shield foam. This makes them more durable for years of hard use like shield rimming, shield bashing, grappling, blocking very heavy pole shots, and any other abuse you can throw at it.
