Within this marketplace, it has become common for the moisture barrier and the thermal
liner together to be sewn together as a unit (as opposed to being hemmed separtately,
since some Moisture Barrier manufacturers require the Moisture Barrier be protected this way). This combined
hemming method offers the important advantages of minimizing liquid wicking up the
thermal liner from the hem and maximally protecting the often fragile moisture barrier
from the contaminates of the fireground.
Unfortunately, the combined hemming also has one serious negative. When the liner
and moisture barrier are hemmed together, it means that the fill of the liner and
the base of the moisture barrier are the ONLY elements of the protective systems
that cannot be routinely inspected in the field. A deteriorated thermal liner fill
could mean sharply reduced thermal protective performance. Similarly, a damaged
moisture barrier substrate could forecast serious leakage and reduced protection.

The Liner Inspection Port offer the advantages of a combined hemming
system BUT also allows effective inspection of the liner fill and moisture barrier
substrate.
Existing Morning Pride garment liners can also be retrofitted with inspection ports.
All BPR garments automatically include the liner inspection port, since continued
bloodborne pathogen resistance is dependent on moisture barrier integrity (as well
as more visible garment design integrity), and can be ordered as an option on LTO
garments.
