Just found this, looks close to Otterbox Defender but maybe not quite as bulky. I had a Trident case on my 928 and liked it.
Cyclops Case for Nokia Lumia 929
I have this case now, but I think I'm going to send it back. I love the profile of the case, but the built in screen protector design isn't right. Since the screen is curved at the edges, it causes the built in screen protector not to make contact at the top, bottom and both sides. It is really bad at the top and if you sweat at all while using the phone, it gets under the screen protector. You then have to remove the phone from the case and clean the under side of the screen protector and your phone/screen protector on the phone if you have one. I asked Trident support via email if it was supposed to fit this way and got a vague answer and an offer to replace it. Instead I think I'm going to return it to Amazon for a refund. Other than that, it's a well built case and I would recommend if this quirk wouldn't bother you. I think I might go pick up an otterbox instead. I'd rather use it naked, but I'm terrified of breaking it.
