Wear several layers of loose-fitting clothing.
The extra layers of air will keep you warmer
than if you wore one or two heavy garments.

W
hat’s your best protection against the cold? The answer is dry air. It’s an excellent insu-
lator. Cold weather clothing—like the extended cold-weather clothing system (ECWCS)—
is designed to trap warm, dry air among its fibers and between its layers. All that trapped
air insulates the body against heat loss and prevents cold injury.

M45 Masks…
Dear Half-Mast,
How do you get an optical insert mount for the M45 mask?
I can't find any info on this.
SP M.P.
Dear Half-Mast,
We've been trying to order M256
simulator detector tickets, NSN 6665-
01-112-1644, but the FED LOG says
the NSN is no longer good. What gives?
G.S.
Dear Specialist M.P.,
You can't find any info on a optical insert mount
for the M45 because there is no such mount. Unlike
the inserts used with the M40 and M42 masks, the
M45 optical insert and lenses is a one-piece system
that fits in the mask. You should get the insert from
the optical lab that provides the lenses for your
unit's M40/M42 masks. If it breaks, get a replace-
ment frame with NSN 6540-01-443-5489. For more
information, contact the Defense Supply Center
(S9M) at (800) 290-8201.
Dear Mr. G.S.,
What gives is that the M256 has been
replaced by the M256A1 simulator detector
ticket, NSN 6665-01-293-2149. Order the
M256A1 instead.
