Favorite Refillable deodorant?

I'm trying to commit to being more earth conscious. I have a plan for most of the replacements in my bath room (shampoo bars, metal safety razors, tooth paste and mouthwash, etc) I'm overwhelmed at looking for deodorant. I usually get the clinical strength stuff (the "toxins" aren't a thing I'm focused on, just reducing packaging). Do you have a favorite or a go to? I'd love to hear your recommendations.
