The NMX created a utilitarian jumpsuit uniform for its space naval soldiers in YE 33.

The new uniform includes:

• Gray Coveralls (5 button front, comfortable, has pants pockets and 2 chest pockets)
  • SMN Flag Patch
• Black leather belt with silver buckle
• Black low-cut boots or black shoes
• White sailor cap with black ribbon (embroidered “NMX” in red. Similar to the Star Army's Service Dress Cap)
• Optional black windbreaker (collared, with zipper)

It is common for the sleeves to be rolled up.

The hat is a white wool cap with a black ribbon around it. The ribbon is embroidered with the letters “NMX” in red.

There is also a gold ribbon version that appeared in YE 33.
