What Are the Best Undershirts for People Who Sweat a Lot?

Do you have memories from a certain big day?

That career-altering presentation that would have been great...if Sally from accounts hadn’t spent the entire time staring at your withering white button-up with the weeping underarms?

Or that day when you thought that it would be a great idea to wear a cotton t-shirt to the gym?

Or that lovely summer afternoon when you decided to wear something light grey to a first date. Near the beach. At lunchtime?

Our bodies have to cool down whenever things get hot internally or externally. Sweat is the result. This means each one of us has a cringey sweat story to tell.

People who sweat a lot are not on their own.

Excessive sweating affects up to 3% of the American population. It is not considered life-threatening, especially if it begins during childhood or adolescence.

However, if someone develops excessive sweat in adulthood, there could be an underlying medical condition. This is known as secondary hyperhidrosis.

Many people affected by sweating too much have been dealing with it for a relatively long time. Sometimes, even when using deodorant or other strategies, sweat can still cause social problems.

Fortunately for the busy man and woman, there are sweat proof garments for this exact reason.

Sweat proof undershirt companies have been changing people's lives for years.

Sweat proof clothing does more than block sweat. It can determine whether a person is going to have a normal day or an unbearable one.

Finding the right sweat proof shirt can be tricky. But here is an overview of what to look for:

All About Sweat-Blocking Materials

To make an informed choice, a person should understand the different types of sweat blocking materials available.

Fabrics respond to moisture depending on their properties. Some fabrics soak it up while others repel it. The main principle behind sweat proof material is all about blocking moisture.

Some examples of natural moisture-absorbing materials include:

Cotton

This natural fiber has been the world’s most preferred fabric for thousands of years. It was the original vest and general undershirt material.

It is one of the most naturally breathable fabrics. Although this breathability allows for air drying, there are a few complications that hinder its usability, namely:

The absorbent nature of the fabric makes sweat stick to the skin.
Pit stains will always be a reality, especially for those who prefer white.
It takes too long for sweat to dry.

Conversely, key favored features found in cotton include:

Strength and durability
Color dye friendly
Retention of up to 27 times its weight in water
Excellent heat retention

Bamboo

Bamboo fabric broadly refers to a collection of different textiles made from the bamboo plant.

Bamboo fabric has existed for thousands of years. But the manufacturing process has become more refined in recent years.

People looking to purchase bamboo garments must confirm that the manufacturer has taken care to ensure environmental sustainability and that their employee’s working conditions are ethical.

Key favored properties in bamboo include:

Ultra-soft material
Mold, bacteria and mildew resistance
Durability – lasts for many washes
Highly breathable
Stretchier and thinner than cotton

Linen

Linen is considered a highly sustainable fabric made from flax fibers. The flax plant has been around for over 6000 years and has been cultivated in almost every country in the world.

Key favored properties found in linen include:

Up to three times stronger than cotton
Quick-drying properties
Natural heat and moisture-wicking properties
Color dye friendly
Natural antibacterial properties

Let’s look at some synthetic water-repelling materials:

Polyester

Polyester is an artificial fabric originally made from petroleum. It is one of the world’s most popular textiles.

This material is quite water-resistant but it does not absorb sweat. Polyester keeps moisture in, which means sweat ends up sticking to the skin or showing up on outer clothes.

Rayon

Rayon is made from purified cellulose fibers found in wood pulp. It is also considered a semi-synthetic fabric due to its chemical properties.

It is one of the most versatile materials in textiles. It can mimic the properties of cotton, wool, silk, and other fabrics.

Rayon does not trap heat. It repels water, making it great for hotter weather clothes.

Cotton/Lycra Blends

As the name suggests, this fabric is a mix of cotton and lycra. The resulting blend offers enhanced comfort and the same breathability as cotton.

However, cotton/lycra blends trap heat and moisture, increasing the chances of sweating, especially with tight clothing.

Choosing the Best Sweat Proof Undershirt

There are key features to look for when choosing a sweat proof undershirt.

Sweat Proof Undershirt

Sweat Proof Technology

All sweat proof undershirts have a particular type of sweat proof technology.

While each brand offers unique products, most undershirts are made with an inbuilt protective layer targeting the main sweat producing areas.

Sweatshield undershirts are the product of ten years of research and technology. The result is an impenetrable sweat-proof underarm barrier.

Sweatshield undershirts are made using the gold standard, ultra-soft micro modal fabric. It is 50% more absorbent than cotton.

And yet, the undershirts provide temperature and moisture control throughout the day thanks to our revolutionary keep-cool technology.

Fabric

As earlier explained, fabric quality makes or breaks a sweat proof undershirt’s efficiency.

Modal and micro modal fabrics work best. They are luxuriously soft, lightweight, and 100% more durable than regular cotton. They can also last a long time with good laundry care.

The right undershirt fabric gives the wearer the maximum range of motion. It should be able to easily stretch around your body without bunching up.

Sweatshield undershirts stay snuggly tucked in. There are no bothersome tags, allowing the wearer to enjoy the confidence of a crisp looking outer garment.

Undershirt Fit

An undershirt’s cut (shape) and length matter a great deal.

Most brands have extra-long contoured undershirts as part of their product offering. These are better at providing protection and invisibility.

A longer undershirt naturally stays tucked regardless of the kind of activities people engage in all day.

Finding the right fit means protective layers in the undershirt will stay exactly where they are supposed to be. This is mainly around the underarms or on the back.

Sizing

You should always check a brand’s sizing guide to find your perfect fit.

For sweat proof undershirts, the right size means all protective layers stay on the areas that need the most coverage.

For maximum overall protection, you may need to look into sizing up. The underarm panels are scaled to size. But larger sizes have a larger protective area and thus, they will offer greater moisture protection.

Color Preferences

The kind of sweat proof undershirt you wear largely depends on the colors you wear daily.

One of the key properties offered by sweat proof undershirts is a measure of relative invisibility. Most brands have varied colors and neckline designs to suit these changing needs.

Sweatshield’s Men’s Sweat Proof Undershirts are now available in three handy colors to suit every occasion: black, white, and beige.

Sweat proof undershirt providers have varied styles as well. Each style has a function in everyone’s closet, i.e:
