This ProTecTOR, with outer felt layer not sewn & folded down, shows what's visible from the top opening as you place Balance Sims over the Patented Protective Shields. You can see some Shims at the top on the other side of the pad shown here.
The Envelope Pads are the same on the outside as are the balance shims and the pocket they are used in. The white felt CorrecTOR is gone and the Protective Shields are placed into the ProtecTOR Pad sewn under the nylon netting you see above. Special collapsible column, open padding a 1/4" thick is under the shields.
