  2. Sizing may be an issue: If you have extremely sensitive skin or certain allergies, you might have to wear a non-waterproof cast.
  3. A waterproof cast takes hours to dry since the only way is to let the water evaporate.
  4. A waterproof cast can’t be put on until 1 to 2 weeks after your injury, so you may need a cast or a splint to keep you protected sooner.

However, it’s still advisable to avoid swimming in the ocean or a pond, so debris doesn’t get in your cast. If you have to, then remember that your cast is waterproof, not sand-proof.

So consider a waterproof cast protector to prevent sand from getting inside the cast.

In general, you’ll have to limit your swimming in all types of water to not more than three hours per swim.

What Are Waterproof Casts Made of?

A waterproof cast has a normal fiberglass outer layer, but instead of a cotton layer beneath it, there is a waterproof liner that does not absorb water. This ensures that it dries more rapidly and can get wet without falling apart.

The fiberglass in waterproof casts is lined with Gore-Tex material.

This type of material repels water and allows moisture to escape. After bathing or swimming, a Gore-Tex liner quickly draws moisture from under the cast and air-dries within hours.

Final Words

For many people, wearing a cast can be uncomfortable. Fortunately, there are a variety of options available now that can help you avoid this.

Some people prefer to wear a regular cast instead of a waterproof cast. However, waterproof casts are more comfortable, more hygienic, and more versatile.

There are several options for waterproof casts out there. The materials used in each of these products vary widely and will depend on which type of cast you need (i.e. a short- or long-term cast).

When you purchase a waterproof cast, make sure to consult your doctor or medical professional to determine which type is right for you.
