My iPhone survived a camping trip earlier this summer. All it was equipped with was an Incipio Frequency (thin-ish TPU case), and Belkin screen film. This is good enough for daily use, but not good against dust, dirt, and rain. I used a ziplock bag on rainy days, which kept the water out, but made the phone more difficult to pocket. I'm looking for a more integrated solution. I want something that will keep rain and dirt/dust out of the phone's buttons and ports. Some of the waterproof cases, like the Lifeproof Fre and Incipio Atlas seem to have usability and quality issues, based on the threads I've browsed. Otter box seem a bit too bulky for me. Lifeproof Nuud looks interesting, but I'm not sure how well the back will resist scratches. I haven't seen much feedback on the newer Ballistic Hydra. Anyone using that one? Any others I should consider?
