Dear Sir:--The Jaros Hygienic Underwear has been in use with us
for last three seasons, and I can highly recommend it to all Fire
Departments, as this underwear is considered by us as the best possible
protection against cold and changeable temperatures, which are
especially characteristic of this latitude, and its use has resulted in
great protection of health and a corresponding increased efficiency,
and I find them the most desirable article I have ever seen for the
object to be attained.
Very truly yours,
JOHN JACKSON,
Chief Engineer.
