Czech Military OM-90 NBC Filter (NEW)

A true Sigma needs a Sigma filter to protect himself.

Yes yes, laugh it up. Sigma is really on each and every one of these filters. They are the supply company behind the OM-90 (Czech Military Gasmask) NBC filters. We got a special little shipment of brand new filters in the shop that won’t last. Specs are available in the gallery. These are NEW and UNUSED. They are in vacuum sealed packaging that include instructions for usage.

These are marked with an expiry date of October 2032.
