Mr. Jaros.
Dear Sir:—I am sincere in expressing a favorable opinion of the "Jaros Hygienic Wear" so far as my experience allows me to judge. The patients to whom I have recommended it are of delicate health, very susceptible to cold. They uniformly expressed themselves as pleased with the garments made for them by you, and as having suffered far less from the cold this winter than usual: a result which they attribute directly to the power of the underclothing to prevent sudden chilling of the body upon transition from a high to a low temperature. Personally, I have worn the underclothing all winter, and believe my unwonted freedom from attacks of bronchitis due to the efficient protection afforded by the underwear. Your cloth seems to me to be a better non-conductor than other woolen materials, and therefore particularly suitable to persons with heart or lung disease.
I am, very truly yours,
Robert H. Babcock, M. D.
