What kind of trousers are you normally wearing? I'm used to wear slim fit jeans or cargo trousers. I think with my cargo trousers there shouldn't be a problem. But putting a 6 inch device with 14 mm of thickness, which sticks inside a pouch in a my jeans is simply impossible. I hope that it will fit in some way in without any case. But I fear even that will not be comfortable. Sometimes my Xperia X (inside a slim case) is already uncomfortable.
