Review: Case Marine iPhone 5 Waterproof Case from



If you haven’t checked out the web site of our sponsor yet – you should!  Many of the super cool brands I’ve reviewed here on Run Around Tech, such as Element Case, Esoterism, OtterBox and more are sold through CaseMotions.

We’ve covered our fair share of waterproof cases for the iPhone 5.  We checked out the Griffin Survivor + Catalyst, the LifeProof Nuud, the Incipio Atlas, the LifeProof Fre and the Dog and Bone WetSuit.  Each of these cases are priced in upwards of $69 or more.  They all do a good job of keeping your iPhone protected while near water and also from shock and impact.  The one thing these cases have in common however, besides being waterproof, is bulk.  The Case Marine iPhone 5 case from not only sells for under $40 but is incredibly thin as well measuring only .25mm when installed.

Read on through for my full review and be sure to catch my video at the end for a more up close and personal look at the Case Marine iPhone 5 Waterproof Case.



Inside the packaging you’ll find the case, which is composed of two parts along 10 sealing stickers and a set of instructions.

Here’s what has to say about the Case Marine iPhone 5 Waterproof Case.

Case Marine is made of ultrathin, double layered thermoplastic polyurethane. It is pulled over your Smart Phone and sealed to be water and airtight on the back side with an elegant premium adhesive tape. The side seam runs on the inside of your skin making it invisible. To ensure premium fit custom.

Case Marine is fully water repellent. Applied and used correctly customers use it as waterproof. We have customers who have used Case Marine diving (max. 10 meters) deep and while swimming without problems. Obviously using on pool edges and in bathtub etc. is no problem and works.



The Case Marine waterproof case is made up of essentially three parts.  An inner membrane.  A sealing sticker and a TPU case.


The first step in placing the case on is to wrap your iPhone 5 in the protective membrane.  This is made from a polyurethane, synthetic nylon resin material.  Case Marine says they hold a patent on both the material and the production process. It is very strong and durable.  Stretch and pull the membrane around your phone making sure that all the ports and controls get lined up.


To seal up the membrane you take one of the sealing stickers and place it over the opening on the back of the membrane.  Press the sticker down smoothing out any air bubbles or wrinkles.  Case Marine says you should only use the seal one time.  You’re supplied with 10 seals with the case and can purchase additional seals from the company’s web site.  Once you’ve got the phone in place and sealed up you can remove the protective film covering the built in screen protector.


Finally place your wrapped phone inside the TPU case to complete the installation.  What you’re left with is one of the thinnest waterproof cases on the market.  I’m a little confused by the TPU portion of the case and whether or not it’s needed.  There’s no mention of it in the instructions.  It would seem to be the TPU case can be used when you don’t need the waterproofing or when you need a bit more shock protection.  The TPU case doesn’t add anything in the way of additional waterproofing.


When fully installed on your iPhone 5 the Case Marine case covers all the iPhone 5’s ports and controls and unlike some other waterproof cases doesn’t allow for access.  This case is all about protection.  You won’t make the mistake of jumping into a pool with your iPhone case that you’ve forgotten to close the headset jack cover on.  For charging and use of earphones you’ll have to take the case completely off.


As far as call quality goes as with all cases there is certainly some degradation of call quality.  Case Marine actually goes as far as to recommend setting your ring volume to a level to the highest level and for maximum call quality they recommend using a Bluetooth earpiece as well.


Case Marine stands behind their product too, offering a full insurance plan for users of their case.  The details on this plan can be found here.  Essentially if the case fails, and you’ve followed all the rules,  you get your device replaced.

The Case Marine Case has been tested and approved for waterproof to 10 meters in depth. It holds an IPX8 certification as well.  This is easily this thinnest waterproof case I’ve tested and the least expensive as well.  While the case does limit functionality of the phone it’s still worth a look for those not needing waterproof protection all the time.  If you’re someone who only takes your phone near water a few times a year this is a great option.  The Case Marine Case is remarkably thin, affordable and backed by the company’s insurance as well.
