Chems are horrid but one can dress for them.
Nerve agent like other war gases degrades opponents by forcing them to wear CBRN ensembles which are miserable to work and fight in. (Gas is so nasty not even Hitler used it in combat because he'd personal experience in WWI.)
Modern CBRN suits are (barely) breathable because they can filter contaminants. Suits which even partly neutralize nerve agent would not just save lives but reduce misery. Gases are frequently inefficient even when used on undefended targets like Saddam Hussein's bombing of Halabja (which took multiple sorties to execute).
A chem suit fabric that can neutralize contamination could save lives and usefully decrease exposure. Chems don't magically wipe out everyone exposed. The 1995 Tokyo subway attack affected several thousand people while only causing ~14 direct fatalities among a concentrated, defenseless group. Neutralizing fabric would be very useful against highly diluted agents.
