Belt? Pockets? Armband?
I've tried a belt (one of those Lycra ones you can flip over) and really like it but the problem is I sweat into it and my phone gets sweaty which is a bit gross!
My preference is pockets but I need to take both a key and phone, and having to wear an outfit with two pockets, and one big enough for a phone, gets quite restrictive in terms of what I can wear.
I haven't tried an armband yet because it looks like it would be really cumbersome and I don't really like advertising my phone to the world.
What do you find works for you?
