>>1182576Go for a softer gel padded saddle if you want to wear normal clothes and not have to change. You'll more than likely be fine on rides of 30 mins or less unless you're bony-assed, fat, or a combo of both.
If you want something for longer trips or harder rides, get some of pic related and a regular touring saddle, race saddles are likely too hard for you for what you need.
Like other anons have said, proper shorts are cheap and you can ride in the worst of weather and need leg warmers/overshoes at the worst. Either option should do fine for such short rides though, up to you really.
