Need to freshen up between showers? Try a couple sprays of Kill It Dead ($12). Billed as a "natural de-funkifier," this mixture of witch hazel, tea tree oil, and other earth-friendly ingredients is formulated to kill offending odors emanating from your underarm, foot, or other stinky spots. A great alternative to traditional aluminum-filled anti-perspirants.
If your shoes tend to resemble the bayou after a long workout (or just a long day at work), pick up some Amenity Foot Spray ($32). With a mixture of Drieline, willow bark, menthol, and clove and thyme, this stuff helps prevent wetness and odor, minimizes crevices on feet, and reduces calluses. The locking sprayer is great for a gym bag.
