Stretch on the Dry Pro over the leg to see how it fits. If the Dry Pro is too tight, you can trim 1/4 in ch along the lines towards the top of the opening and try it on again. Be sure not to trim too much, as a tight seal is needed for the vacuum to work. Stretch the Dry Pro over the prosthetic so the top fits smooth against the skin. Allow some slack as the vacuum will remove the excess material.

Slide  the protector over the prosthetic limb so that it is completely covered. The Dry Pro should fit snug and comfortable on the upper leg. The opening should be flush along the skin. Make sure to pull the boot flat against the sole so the bottom of the protector with the Non-Skid Grid lies flat against the ground.

Continuously press the pump until all the air is evacuated and the pump becomes flat. Move your arm around and make sure the seal remains intact, then remove the pump and put the cap on. After creating the vacuum seal, observe the Dry Pro for about 5 minutes before going into the water.  In order to remove the Dry Pro simply slide your fingers under the top cuff to let the air in and slide it off.
