I would suggest that you buy neither of the two or any other "scent eliminating" JUNK. The carbon stuff does not work as advertised and you can achieve good "scent control" by washing clothing in baking powder/scent reducing detergent, properly packaging cleaned clothes, only put on clothes when in the field, shower using scent reducing soap/shampoo, use scent reducing spray on self and equipment when in the field and pay attention to the scent you could bring out with you.
Playing the wind is the best idea.
Save yourself a lot of money and don't buy a fraud.
