The Problem: Axillary Hyperhidrosis

Sweaty armpits, excessive underarm sweat, sweaty underarms, pitting out, wet marks … call it what you want, but know that you are not alone. Everyone sweats; in fact about 35 percent of adults experience at least one weekly “sweat event,” (defined as feeling underarm wetness). Billions of dollars are spent every year on antiperspirants for sweaty underarms. (If you’re reading this, chances are, nearly every antiperspirant has failed you in one way or another.)

Axillary Hyperhidrosis is a condition marked by excessive underarm perspiration beyond physiological necessity and with no proven cause. Unfortunately, it is not a temporary condition. Many people who suffer from it have suffered for many years, usually beginning in puberty and lasting into late adulthood. Also, whether in a hot or cold climate, the sweating is constant. Often, Axillary Hyperhidrosis sufferers are not taken seriously by their families or medical practitioners, who downplay their problem's significance because it is not life threatening; they view the consequences as insignificant. However, the many people who endure unimpeded, intense underarm perspiration must cope with constant embarrassment, frustration and stress. Frequently perceived as being ill, nervous or lacking in confidence, they often experience social and professional problems that seriously affect the overall quality of their lives.

Treatments vary, but unfortunately there is no permanent safe solution for Axillary Hyperhidrosis. Various methods are available, but not without adverse side-effects and mixed results. The world's best sweat proof shirt, The Thompson Tee with Hydro-Shield Sweatproof Technology, is truly a special sweat proof undershirt that offers a convenient, inexpensive, effective, and natural solution to alleviate the stress and embarrassment from 'wet marks,' stained clothing, and the insecurity associated with
sweaty armpits. Many of you are already wearing a traditional undershirt or t-shirt so there is no change to your everyday habit—you simply continue to put on an undershirt—one that comes with a sweat proof Guarantee, backed by proven Sweatproof Technology! ( Learn more)
