Would the Filtered Rebreather armor upgrade negate the Fort save for being caught in the smoke from a smoke grenade? Or is the bit about filtering poisonous vapors fluff text?
My understanding is that any armor provides enough environmental protection to negate the smoke from a smoke grenade.
Smoke grenade, pg. 184:
A smoke grenade deals no damage; instead, it releases a cloud of
dense smoke. Each character who inhales smoke must succeed
at a Fortitude saving throw each round (DC = 15 + 1 per previous
check) or spend that round choking and coughing; he can do
nothing else. A character who chokes for 2 consecutive rounds
takes 1d6 nonlethal damage. (Active environmental protection
from a suit of armor prevents this effect altogether.) Regardless
of the armor a character wears, smoke obscures vision, granting
concealment to anyone within it.

Armor Environmental Protections, pg. 196:
Space can be an inhospitable place, with countless dangerous
worlds within it. Unless otherwise specified, all armors protect
you from a range of hazards to ensure that you can survive for
at least a few days if you must make emergency repairs to the
hull of a starship, explore an alien world, or endure exposure
to an environmental breach in a space station. Some armors do
this through an environmental field (a minor force field specially
attuned to pressure and temperature that does not reduce
damage from attacks), while others can be closed with helmets
and airtight seals. The most common environmental dangers are
detailed in Environment beginning on page 394.

The purpose of the rebreather is to extend the environment protection from 'days per level' to 'weeks per level', and improving resistance to acid and poison.
Failure to read on my part. Thanks for pointing that out! I read that paragraph two or three times and it never registered.
