The USGI Woodland MOPP (Mission-Oriented Protective Posture) Suit, commonly known as the Battle Dress Overgarment (BDO), was once a critical piece of gear for U.S. military personnel facing chemical, biological, radiological, and nuclear (CBRN) threats. These suits played a pivotal role in military operations during the late 20th and early 21st centuries.
 
While no longer viable for CBRN defense, their vintage nature makes them ideal as collectibles, rugged workwear, or even outdoor gear for hunters. Washing these suits in water is not reccomended due to the charcoal lining.
