Regular lightweight camo washed in unscented laundry detergent like Sportwash followed by a rinse with a box of baking soda in the water will provide more than adequate protection . Remove the clothing before the rinse cycle ends , wring out the excess water , then hang the garments to air dry outdoors . This will leave a residue of baking soda in the cloth that will absorb odors without adding weight . Cheap , simple , and it works at least as well as the more expensive clothing . Don't forget the unscented underarm antiperspirant .
