Best Roll-On Deodourant: Kosas Chemistry Deodourant We love the Kosas Chemistry Deodourant ($15) for many reasons. The formula is a clear gel that doesn't stain clothes, the roll-on applicator makes it easy to apply, and the blend of acids help get rid of any odour — yes, even after a hard workout.
