Any model, 6, 6+, S series. Even 5 series Most threads are looking for that ONE perfect case! Holy Grail kind of thing But let's face it, we don't wear one pair of shoes (dress, casual, sneakers, hiking, sandals). The same with clothes. So I've noticed more and more forum members are doing rotation cases. List yours and when you use them. Here are mine: KAVAJ Tokyo for most days. Office work, around the house. Shows off the phone and direct button access. TECH 21 Evo Mesh (Apple store version). For outdoor yard work, sticky wet hands, more active days. KAVAJ Dallas case. Has a flip cover ( I don't use screen protectors) , for Gym. On the tread mill, weight lifting. The flip and pockets are perfect. Miscellaneous cases: Apple leather and Sena Heritage sleeve. Random use. I think rotating cases is the smarter solution than buying dozen of cases looking for the ONE. Share yours!
