  • Carefully grip the H₂O Shield™’s navy blue neoprene seal by its outer edge using your thumb and forefinger, where it joins the clear plastic body of the protector. Insert your arm into the seal opening, gently pushing it in.
  • Still gripping the H₂O Shield™ as described above, continue dragging it up and slowly ease the navy seal over the affected area. Then allow the seal to turn inwards as it slides up to secure it.
  • When you’ve pulled the H₂O Shield™ up as high as possible, pull the H₂O Shield™ down slightly so that the seal reverses itself, turning upwards so that the inner surface of the seal is in direct contact with your skin
  • Ensure that the seal of your H₂O Shield™ lays flat against your skin and is wrinkle-free with a snug, comfortable fit to ensure waterproof protection.
  •  Carefully roll the seal back on itself a little and ease it over your dressing
  • You will now be able to slide the protector off your arm easily
  • Hang your H₂O Shield™ to dry - ensure it’s away from any direct heat source.
  • It will be ready to use again whenever you need it
  • Hand-wash the H₂O Shield™ as needed
  • You can use a mild disinfectant or detergent.
  • Dry your H₂O Shield™ thoroughly away from direct heat before storing.
  • Avoid folding the neoprene seal and check that it remains undamaged before reusing
  • Store in a dry place at room temperature

Helpfulness: Cast covering
SO GOOD!

I am in a long, rigid splint after wrist surgery and soon to be in a long armed hard cast for several more weeks. I bought 2 different cast covers from Amazon and Walgreens, and one was too short and the other had too tight an opening to fit around my giant splint.

I just used this Mighty Well cover and could easily get it around my cast without causing a bunch of jostling or pain. It kept everything SUPER dry, and it makes a huge difference having the opening sized and stretchy neoprene. It was also plenty long enough to cover my whole arm (I'm tall with long arms). I ponied up and paid for faster shipping and it arrived on time.

I can't recommend this enough!!!!

Thank you so much for the enthusiastic review, Jenna! We are thrilled to hear that the H₂O Shield™ made showering painless after your surgery and easily stretched over your long splint while keeping everything completely dry. Navigating recovery after wrist surgery is tough, so knowing our stretchy neoprene opening, full length, and fast shipping brought you that much-needed relief means the world to our small, women-owned business. Thank you for recommending us so highly and for being a fantastic part of the Mighty Well community—wishing you a smooth and speedy recovery!

Lifesaver for hand in a cast

This waterproof cast cover made taking a shower much nicer while in a cast! There was plenty of room, but the top cuff chaffed on my arm no matter where it was placed. Still, was a great solution to taking a shower while in a cast!

We're grateful for your feedback and delighted you're enjoying Mighty Well!
