I have bought the best woolen and heaviest silk underwear in prominent cities where I have travelled, abroad as well as in this country, with the special view of getting something that would protect me while in my rubber dress, on the long, cold and damp voyages I make. The exercise and heavy rubber suit which I wear often cause active perspiration, and my observation has been that from one to one and a half pounds of moisture is thrown off during an exhibition lasting from one and a half to two hours. With all other kind of underwear, this moisture was taken up only partially, the garments becoming thoroughly wet, and causing a chilling which was always hard for me to overcome; in fact, after these aquatic exhibitions, I found it absolutely necessary to be well rubbed to draw the blood to the surface and produce reaction, to prevent trouble. I speak of other underwear to give you an idea of this action, and the difference in the body under trying conditions. Your wool I found admirably selected and prepared, and so incorporated to act quickly and absorb the moisture thrown off. My experience is that the "_Jaros Hygienic Underwear_" does not only relieve the body of perspiration, but also carries it to the cotton framework outside, which thoroughly retains it, thereby keeping the wool inside perfectly dry. Since I began to use the underwear, I have never felt the chilling which had always affected me with other underclothing, and I do not find rubbing after an exhibition necessary. I have no trace of rheumatic pain, and I feel physically much better. The difference in the amount of perspiration seems to me marked, which I attribute to the fact that the body temperature remains more nearly the same. I am so well pleased with your underwear, that I use it for general wear as well, and find every point you have claimed to be realized in its use. In conclusion, I can say, that your underwear is a boon and blessing to men exposed as sailors, firemen, soldiers, and as well as the general public. Wishing you the success you deserve, I remain, yours very respectfully, PAUL BOYTON. * * * * * We refer with permission to the following chiefs of Fire Departments, who use and recommend this wear for its value in Department service: Chief Hughes Fire Dep't, Louisville, Ky.
