Starfleet's midlevel suit is the standard extravehicular work garment (SEWG). This type is reinforced with additional radiation and pressure layers for extended operations, and is configured with a sixteen-hour consumables supply, plus enhanced recycling devices. It is designed for most major industrial tasks and hazardous exploration assignments. Radiation and micrometeoroid protection is essentially unlimited. The suit controls are supplemented by advanced autonomic life support controllers within the suit computer.
