Sweat Proof Undershirt

0

Hyperhidrosis is annoying, but manageable with some planning. Excessive sweat friendly clothing is one of the many tools in your arsenal to manage your sweat. This post will tell you all you need to know about Sweat Proof Undershirt – one of the most effective options for managing excessive underarm sweat.

Sweat Proof Undershirt – What is it?

Let's start with basics. A sweat proof undershirt is essentially an undershirt that has special technology/construction to – a) prevent sweat from oozing to outer clothing and b) keep you cool so that you sweat less in first place.

One of the common misconception about sweat proof undershirts is that they prevent you from sweating. Strictly speaking, that is not true – while the fabric and construction is usually designed to encourage breathability, the focus is more on “proofing” the undershirt so that the sweat does not enter the outer clothing to cause sweat stains.

An important distinction, at least for this blog, needs to be made between sweat proof undershirts aimed at excessive sweat with advanced technology vs. more general purpose undershirts that are designed for breathability. Some products market themselves as sweat-proof undershirt for hyperhidrosis patients while they are essentially a general purpose undershirt.

Below are few pics of sweat proof undershirts from various brands:

How does Sweat Proof Undershirt help?

As mentioned earlier, a Sweat Proof Undershirt keeps the sweat generated by body from getting to the outer clothing. This ensures that your shirts/dress etc do not show the ugly sweat marks. They also help avoid the yellow sweat stain that people with hyperhidrosis are only too familiar with.

To be clear – sweat proof undershirt is not a treatment of hyperhidrosis. They will not cause you to sweat less, they will just help you manage the sweat better and live a normal life without the fear of sweat marks showing and damaging your pretty dress!

How Do Sweat Proof Undershirt Work?

There are several products in the market that would qualify to be termed as Sweat Proof Undershirt for hyperhidrosis patients who sweat excessively in the underarm and upper body region. While almost all of them claim to have a unique (or patented) technology that makes them the best choice, most of them have pretty similar underlying technology.

Breathable Fabric – A good Sweat Proof Undershirt is made up of breathable fabric. Most commonare cotton, and modal, but other fabrics can also be used.

Sweat Barrier – the secret sauce is the sweat barrier in targeted areas (mostly underarm, but sometimes also on the back or everywhere). In the targeted area, the undershirt has 3 layers instead of 1 – the inner layer, the middle layer and the outer layer. While the inner layer and the outer layer are made up of standard material (e.g.cotton/modal), the middle layer is the “sweat barrier” that keeps the sweat in and does not allow it to escape to the outer layer. The material for the middle layer can also differ  – but several manufacturers use bamboo fabric that also has antibacterial properties that keeps the odor in check.

Sweat Proof Undershirt – What You Need To Know

Sweat proof undershirts are great – however, there are a few things you need to know if you are considering them to manage excessive sweat:

  • Sweat proof undershirts can be quite expensive – some can run as much as $30-$50 per undershirt as compared to sub $5 pricing for a normal undershirt.
  • Most sweat proof undershirts target the underarm area – if your area of concern is different (e.g. back, or entire trunk), you need to select the undershirt which provides the sweat barrier for those areas.
  • Sweat proof undershirts are bulkier than usual undershirts. Thats is not a big issue, but you need to be aware of that. Many users express surprise at how bulky they feel if they have not used them before.

Taking care of Sweat Proof Undershirt

A Sweat Proof Undershirt should be reasonably expected to last a year or more depending on the usage intensity. However, you may extend the life (and ensure good performance) by taking good care.

Most sweat proof undershirts can be machine washed (cold or warm water) and dried in a dryer or line dried under sunt. You should turn the undershirt inside out when washing/drying to ensure that the innermost layer (the one that is exposed to the skin) is cleaned well. You should also avoid sleeping in a sweat proof undershirt as sweating is usually not an issue while sleeping and by taking it off in the night, you can extend the life of sweat shirt significantly

Unless indicated by the care instructions provided by manufacturer:

  • Do not use any bleach or any bleach byproducts in the detergent, as bleach can  compromise the sweat proof layer rendering the shirt useless as sweat defence.
  • Similarly, never dry clean your sweat proof undershirt dry cleaned. Just like bleach, the chemicals used in dry cleaning may compromise the sweat proof technology.
  • Also, do not iron the sweat proof undershirt, as direct heat can compromise the sweat proof technology

How to use Sweat Proof Undershirt

Its like wearing any other undershirt, with a few important considerations:

  • While washing, apply detergent directly to the underarm or other target areas. Since the sweat proof undershirts are designed to trap sweat in, they require more than usual care to ensure that its clean
  • Before wearing the shirt, apply a good antiperspirant – while not required, this will reduce the sweat production itself, ensuring that your sweat proof undershirt has to do less work to keep you looking fresh!
  • When you take off the shirt, take care to keep it outside in to allow the inner fabric to breathe and get exposed to fresh air.
