  • Arm Circumference Measurement 
Measure the circumference of the Arm right above the cast. (If the end of the cast is very close to the elbow, measure mid bicep). 
  • Arm Length Measurement
Measure from the tip of middle finger to top end of cast. It is OK if the cast protector measurement is longer then the limb measurement, the protector will still work. Extra length will be removed when the vacuum seal is created.

Half Arm Waterproof Cast Cover - Large


Product Description

Dry Pro™ by Dry Corp, is the leg and arm protector with the patented watertight vacuum seal. Dry Pro™ fits snug, yet comfortable during a shower, bath, and even an active swim. Unlike "modified garbage bag" products, the patented vacuum seal ensures watertight protection. Dry Pro™ products are made of high quality surgical latex; which undergoes a chlorination process to remove the allergens in the latex preventing any allergic reactions. 

Using Dry Pro™ products are as Easy as 1-2-3!

1. Slip it on: Stretch the Dry Pro™ over the arm or leg cast, bandage, or prosthesis.


2. Make it air tight: Pump out the air using the removable hand pump that is included


3. Taking it off: When you are done, simply let the air back in by lifting the Dry Pro™ from the skin, releasing the vacuum seal and slide it off.

So go ahead and ENJOY THE WATER!
