Phone bag for teen DS?

[Shufflebumnessie]

I've seen lots of teen boys wearing what look like small, cross body phone bags. I think DS would find one useful but I have no idea what brands are deemed to be 'in'.
Adidas? Nike? Or other?
DS really is only just beginning to take notice of brands that teens like so he isn't much help, but for various reasons I'd like to get him something that makes him feel like he blends in.
Any help gratefully received. Thanks

You need to ask him what’s in at his school as it varies regionally from what I see on these threads.

Agree, I’d ask him if you can. I have a teenage boy and everything is black and Nike. Everything. Impossible to mess up you’d think but now and then I buy him something black and Nike and it is too “road man” and he won’t wear it. The rules are incomprehensible.

I'd get him to look and buy later. Mine has a mix of Nike and Adidas stuff.
They are great little bags especially for summer when they don't have a big jacket with pockets for phone.
