With threats of a mustard gas attack on U.S. troops re-emerging in ISIS-infested Iraq, a leading clothing technology company has developed an ingenious way to protect troops from the horrors of chem-bio warfare.
Known more for its waterproof and breathable coating for rainwear and other outdoor equipment, W.L. Gore — the folks who make Gore-Tex — has developed a next-to-skin clothing system that protects against both chemical and biological warfare agents with just a thin layer of its so-called "Chempak" material.
So, say goodbye to that hot, bulky, carbon-impregnated MOPP suit.
"The big thing you think about with chem-bio suits is the thermal burden," said Gore's Mike Merrick. "You want to make sure you're keeping that user as effective as possible which means you have to relieve heat stress and reduce that mobility restriction. That's how we've designed this garment — to address that mobility restriction and range of motion and thermal burden."
The new Chemical/Biological Protective Clothing System developed by Gore is light, stretchy and thin, so it allows the operator unrestricted movement when things go kinetic. Gore also claims it 20 percent cooler than the current chem-bio suit.
The best part is most observers would have no idea a soldier is wearing it, so for public events where security is worried about a potential terrorist attacks, the crowd won't freak out seeing troops or police wearing bulky chem-bio space suits.

"The benefits of this is it's very concealable you could be wearing it under your clothes right now and I'd have no idea," Merrick said during an interview at the annual Association of the U.S. Army conference in Washington.
"Think of something like the Olympics where you don't want to alert a stadium full of people that their could be a threat — you don't want to walk around there in a big chem-bio suit," he added. "But in the event something happens, you have a backpack, you pull a mask on you put gloves on and you're good to go."
Another advantage of the Chempak material, Merrick says, is that it protects against both vapor-based chemical warfare agents as well as liquid-based biological weapons which the current MOPP suit does a poor job repelling.
Gore has also developed a more robust system that includes a one-piece Union-Suit-like undergarment and a thin coverall. The advantage with this option is that it can be doffed and donned over a trooper's uniform and can be configured for different missions depending on the environment. The inner protective layer can be worn under a coverall that matches the camo pattern of the service or agency, for example, rather than forcing units to buy entire suits in one color or pattern.

"The benefit is that it's got this removable outer shell. So that's good for tailorability to the unit," Merrick said. "If they want to change that outer garment for a jungle uniform or you're Coast Guard and you're doing a drug interdiction mission — its' one chem-bio suit with two different outer garment coveralls, so the logistics burden is reduced and you don't have to carry two different chem-bio suits."
American special operations units are already wearing the two-piece chem-bio undergarment on some missions, but Gore is gunning for the Pentagon's replacement for the dreaded MOPP suit.
