This pack is, in some respects better than the last, since it is less
liable to form creases, and the upper portion may be changed more
frequently for the purposes of cooling, than the undivided pack. It is
used together with the abdominal pack.

Instead of using one strip 4 to 6 inches wide, folded 4 to 6 times, as
for the shoulder pack, two strips are taken. One strip is passed across
each shoulder, and crossed on the breast as well as on the back. The
woollen strips used for covering are of course wider and of double
thickness. The ends of the two strips are drawn underneath the abdominal
pack, and held by it, and the two shoulder packs may be changed as often
as necessary for cooling purposes without necessitating a simultaneous
change of the abdominal pack.
