2 1/2 weeks ago, I started going for short (25-40 minutes) daily morning runs. Right now the temperature is mostly 10C or higher, so I can just wear shorts and a t-shirt. One day it was below 8, felt a bit cold, and so I got a functional (=plastic) sport long sleeve. That works well, and I can even wear a t-shirt under it if it gets colder (tested it, currently too warm, but I'll probably do that for 6c and lower). Cleaning is easy, I just take it in the shower with me.

But now I'm worried about it getting colder, not running, getting out of the routine and not starting again.

What does one get for temperatures around 0 or slightly below, that's also cleanable and dryable for the next day, that preferably also doesn't break the bank?

Edit: just to clarify, mainly looking for pants, but will happily take top recommendations as well.

edit2: Just wanted to say thank you to everyone here :) I got a merino beanie and a running windbreaker with a neck-protection. I’ll get running tights if I start feeling the need for them.
