Waterproof cast materials are not really waterproof, rather they are water resistant, and don't fall apart if wet.  A normal fiberglass cast has cotton padding under the cast.  Waterproof materials are synthetic alternatives to cotton that will dry off if wet.

Pros

  • Allows your cast to get wet
  • Keeps odors/smells from becoming as much of a problem

Cons

  • Can be expensive, and not typically covered by insurance
  • Can take a long time to dry

Description

  • Casts are a nuisance, for many reasons, in part because they need to be kept dry...until now.
  • Waterproof cast materials can allow you to get a cast wet without damaging the cast.
  • Waterproof cast liners help you maintain your usual routine activities.
  • You do not have to worry if you're around water, or if your cast gets dirty.
  • Drying the cast liner can take time (even several hours)--it can be like wearing a wet sock.
  • Waterproof liners only work with a fiberglass cast; plaster casts must be kept dry.

Guide Review - Waterproof Cast Liners

When a fiberglass cast is used with a waterproof cast liner, water can drain from the cast and the padding will remain in tact. Prior to the development of these waterproof and breathable paddings, casts were padded with cotton. While cotton can be comfortable, it does not tolerate water, and tends to collect sweat and odors over time. Because of this, the only way to clean the extremity was to see the doctor, have the cast removed, wash the skin, and have a new cast placed.

Waterproof cast liners are a breathable and waterproof underpadding, that withstands water, and allows bathing, washing, and swimming. The cast liner allows water to drain from under the cast, and then air dries, usually within a few hours.
