Thanks for replies so far.

I live in a city where useful items left on one's locked up bike - saddle, front light, back light, water bottle, etc. - are tempting to thieves.

So, I would like for the pannier or basket that I get to look like something nobody wants to detach and steal. (I want to be able to leave it on my bike - I hate the idea of having to detach a pannier and take it with me EVERY time I lock up my bike!)

Anything nice that folds over, or looks like a backpack, just looks to a thief like...A nice backpack that might have some nice stuff inside it. Stealable.

I like the very basic canvas grocery panniers and the basic baskets, because they won't look like anything special to a thief.
