Free 2-Day shipping (U.S. only)

OtterBox.com is the only place you can go to build a custom Defender Series Samsung Galaxy S3 case. The Defender Series offers 3 layers of protection so you don’t have to fear the inevitable oopsie or accident. The two piece polycarbonate inner layer snaps together around the device to form a secure foundation. The inner layer includes a built-in screen protector that prevents scratches while memory foam pads cradle the device to provide added shock absorption. The outer layer is made up of rugged silicone that wraps around the inner layer to absorb impact. The Defender Series Galaxy S3 case comes with a ratcheting belt holster that can also double as a viewing stand.

Rated 4 out of 5 by Protects my phone! I love the design options and though I like the case as far as, it's protecting my phone highly against drops and even being dunked in water, I hate how fast the Camo case stretches out. I have tried one other case that doesn't use the same material as the camo case does and it's much more durable. I think overall Otterbox as excellent cases and they are good quality overall. I think they have excellent customer service agents who answer calls quickly and you basically get free replacements for the life of your phone without having to mail in the phone case January 8, 2015
Rated 3 out of 5 by Has some issues. Just got the new case for my Galaxy S3. It has four cons. First, if you ever need to take the phone out of the hard case you WILL end up breaking off most of the plastic clips around the edge. I got mine together and then seen a lot of dust and debris under the screen protector. I pried apart the case which broke off the clips. Only two are intact. Second, I could not keep the inside of the screen protector free of dust and debris. It attracts that stuff like a magnet. I ended up just removing the screen protector. I read some reviews that it scratches up easily anyway. Third, it takes a lot of effort to press the phone buttons on the edges. Plus there's a lot of play before the rubber touches the phone buttons. Fourth, it takes both hands to remove the phone from the holster. And sometimes I have to check if the phone is snapped in all the way. I'm thinking of getting an oversize soft holster to carry it. December 12, 2014
Rated 2 out of 5 by So So My wife and I both purchased the Defender series cases. It has protected the phones on plenty of drops, but the outer silicone part is in bad shape. The tabs have torn off and the cases no longer fit tight on the inner cases. I will be looking at other cases the next time. November 29, 2014
Rated 5 out of 5 by Dog Teeth I love my Otterbox Defender. I drop my phone continually. Its just something I do. The Otterbox Defender has been wonderful. Yesterday, I dropped it and didn't realize it. Well, it doesn't survive dog teeth. It has kept my phone scratch free and bump safe for a year now, but it could not survive my dogs teeth. I will purchase another one, once I figure out if I am fixing my current phone or buying a new one. November 19, 2014

The belt clip is ABSOLUTELY available. If you don't want a clip, go with the armor series.

In order to order this case the build your own it comes with the clip. Obviously the clip is out of stock. If you don't use the clip put it away or sell it to some one that have the same case and may need a spare clip.
