The boys from Milcomp visited us in order to test the APC556 PDW. Here is their review:
The right functional (under) wear is very important wearers performance. Functional wear from Armadillo, made from high quality Merino wool, offers outstanding isolation while draining sweat fast and effectively. Compared to synthetics Merino wool does not melt when exposed to heat (firefighters/soldiers) and therefore protects the wearer. Besides that Merino wool prevents unpleasant odors when the garment has to be worn for longer period to times.
