According to the external dimensions of an iPhone should fit 6+ incl. Protective case in his pocket. Unfortunately interior are at the seams thick ridges that reduce the clearance height so that the zipper can not be closed. Who his iPhone 6+ "naked", and therefore in the bag fits, used should not have any problems, because the bags are soft lined. Since I am dressed accordingly in the rain, the water-permeable zippers were not relevant for me. So if you can live with the fact that the Smartphon protrudes above from his pocket and the same is not waterproof, is well served.
