Miessence Roll-On Deodorant

This is probably the only natural deodorant that really works.  It comes in three scents, Ancient Spice, Tahitian Breeze and Aroma Free. The Ancient Spice (more masculine) and Tahitian Breeze (more  feminine) are a bit herbal smelling at first, but the aroma doesn't linger.  Aroma Free is just as effective, without any scent.  I have tried just about every natural deodorant on the market (even some you've never heard of), and this is the only one that is at all effective, and it has a great safety rating on EWG Cosmetics Safety Database. 

I used to work a 5 hour shift in the HOT FLORIDA HUMID outdoors at a botanical gardens, planting plants. Dirty, HOT, work, did I mention HOT? Though this product will not stop you from sweating (which is actually good, healthfully speaking) it did stop odor. I never felt like I stunk after my icky, dirty, shift.
Me lovey the tahitian breeze.

This has been the best "green" deodorant that I've tried.  I think it is as good as you can get without an aluminum containing antiperspirant.  It's small for the price, but a little seems to go a long way. It leaves you with a decently fresh feeling, however, I'd recommend getting the unscented version. 

The Tahitian breeze scent is pretty unpleasant as far as I'm concerned.  Sure, it is less strong after it dries, but it is the more unpleasant parts of the scent that stick around, including to your clothes even after you are done wearing them.  So, this deodorant is not great if you want to wear a shirt more than once without washing it, even compared to going sans deodorant on a normal day (yes, I did try that).  It has a spicy, almost peppery scent, which I think comes in part from the geranium oil, though I also am not a fan of the patchouli component.  To me, it just has the scent of  plants that have natural chemical deterrents against insect herbivory (i.e. they produce stuff to make them taste and smell bad so they don't get eaten), not a pleasant, inviting floral scent like you would imagine from a name like "Tahitian breeze."  That part is too bad, because otherwise it would be a fantastic product.
