Under Armour Clothing Washing & Care Instructions

May 26, 2023

Under Armour is a sportswear company that sells a variety of clothing, footwear, and sporting gear.

It was founded by Kevin Plank in 1996 and started as a small business – one that he ran out of his grandmother’s basement.

under armour founder kevin plankPlank was tired of dealing with sweat-soaked shirts and wanted to create his own moisture-wicking activewear. After graduating from college, he developed his first prototype, which he sold from the trunk of his car.

Before he knew it, the brand had grown tremendously. He landed contracts with football teams such as Arizona State and NC State and sales exploded.

By the late ’90s, Under Armour was generating over $100,000 in profits.

As of 2024, the company serves over a dozen countries including South Korea, Hong Kong, Germany, France, and Canada.

The Different Fabrics of Under Armour

Under Armour has several proprietary fabrics, which they use for their products. Here are some of them:


HeatGear is designed to keep you cool and dry throughout your workout. It’s also super breathable and allows sweat to easily come to the surface, which helps to regulate body temperature.

In addition to HeatGear, there is HeatGear Armour, a line of base layers that serves as a “second skin.” They’re soft and lightweight and provide just the right amount of support with high comfort levels.

On top of that, there is HeatGear Amourvent, the most breathable fabric that the company has ever put together. It features Mesh Technology, which is light, durable, stretchy, and fast-drying.


ColdGear allows athletes to stay active, even in cold weather. Not only is it designed to wick away moisture, which increases comfort levels, but it also helps to maintain your core body temperature.

In addition to regular ColdGear, there is ColdGear Infrared, a line of apparel that comes with a special thermo-conductive coating that helps to retain body heat.

UA Base

UA Base is unique in that it features a grid pattern, which traps body heat, and circulates it for lasting warmth, even in the coldest of conditions.

There are four different “gradings”: 1.0, 2.0, 3.0, and 4.0.

1.0: Designed for intense activity in cool conditions
2.0: Designed for moderate activity in cold conditions
3.0: Designed for intermittent activity in extremely cold conditions
4.0 Designed for the coldest of cold

UA Threadborne

Threadborne is one of their most comfortable fabrics. It’s nearly seamless and provides a soft, almost cotton-like feel against your skin.

Not only that but it’s also guaranteed to keep you cool and dry during your workout.

UA Storm

UA Storm is designed to keep you warm and dry in wet weather conditions. There are three levels of protection:

UA Storm 1: Fabric is water-resistant
UA Storm 2: Fabric is windproof and highly water-resistant
UA Storm 3: Fabric is both windproof and waterproof

How to Wash Under Armour Clothing

Caring for your Under Armour garments is key if you want them to last. Take sports bras, for example, they should never be put in the dryer as the heat can cause the elastic to deteriorate.

Here are the washing instructions for some of their most popular products:

Washing Under Armour Leggings, Yoga Pants, and Tights

how to wash under armour leggings and yoga pantsFirst things first, turn the bottoms inside out – that will protect the outer layer during the wash cycle and expose the dirty, inner layer to the detergent.

Next, place the leggings in a laundry bag; that will provide another physical barrier so that they won’t wear out during the wash cycle.

Measure one scoop of ACTIVE Detergent, pour it in, and start the machine. Be sure to choose a delicate or gentle setting to minimize wear and tear on your leggings. Skip the bleach and fabric softener.

Once the wash cycle is finished, take your leggings, tights, and yoga pants out of the washer and hang them up to dry.

Alternatively, you can put them in the dryer on low heat. Keep in mind, however, that the high temperature can damage the fabric over time. Avoid using dryer sheets as they will coat your clothes with potentially harmful chemicals.

Washing Instructions for Under Armour Tank Tops, Short and Long Sleeves

Pre-treating Under Armour Tops

In a sink or a tub, mix one part of white vinegar to four parts of water. Alternatively, you can use a gentle cleaner such as ACTIVE Detergent.

Put the items in the solution and let them sit in the soapy solution for half an hour. That will help get rid of any smells.

All that’s left afterwards is to rinse them with water.

Machine Washing Under Armour Tops

Put them in the washer and add one scoop of ACTIVE Detergent powder. Skip the fabric softener and bleach.

Choose a gentle setting and machine wash cold.

Once the wash cycle is complete, take out the tops and hang them up to dry in a well-ventilated space.

While you can put them in the dryer, it’s best to air dry the tops as high heat can cause the fabric to deteriorate prematurely.

Hand Washing Under Armour Tops

Fill a tub or sink with water and mix in a bit of ACTIVE Detergent powder to create a cleaning solution.

Turn your tops inside out to expose the dirty layer and place them in the sink, making sure all of the fabric is saturated with the mixture.

Let them soak for 20 to 30 minutes.

Gently rub the fabric with your hands to remove any loose oils or dirt. Avoid twisting or wringing the fabric as that can cause the material to stretch.

When you’re sure they are clean, rinse them with clean water. Once all the soap is out, you can hang them up to dry.

Washing UA Sports Bras

Machine Washing Under Armour Sports Bras

Next, turn the sports bra inside out and place them in a mesh laundry bag.

Place the bag in the washer and add one scoop of ACTIVE Detergent powder to the basin.

Set the washing machine to a gentle cycle and run a cold water wash. Wait for the cycle to finish before opening the door and retrieving the bras.

Don’t put them in the clothes dryer. Lay them flat to dry instead. Alternatively, you can let them air dry on a drying rack.

Hand Washing Under Armour Sports Bras

Hand washing is the best option if you want your sports bras to last a long time.

Start by creating a detergent mixture. To do that, fill a sink two-thirds full with warm water and add a bit of ACTIVE Detergent.

Dissolve the powder by agitating the water with your hands.

Once it’s thoroughly combined, place your sports bras in. Remove any padding, if necessary.

Let the sports bra soak in the detergent solution for at least 20 minutes before rinsing clean with water.

Allow it to air dry afterwards.

How to Clean Under Armour Underwear

To prevent their underwear from losing their shape, it’s best to put them in a mesh lingerie bag.

Make sure the bag is zipped up all the way and place it in the machine. Select a gentle cycle and pour one scoop of ACTIVE Detergent powder.

We recommend running a cold wash cycle as you don’t want to expose delicates to heat.

Once the washing is complete, let the garments air dry.

    Hi my shirt gets bad odor when I sweat even it is anti odor. How do I get rid of it. Does it have something to do with washing?

      Hi Micee! Have you tried using ACTIVE Detergent? Our enzyme formula is designed to target sweat and other residues that are embedded into the fabrics. This removes odors at the source instead of just temporarily covering them up like other detergents!

    I have a hoodie which is the “Storm” material brand. This is ‘Water resistant” which makes is almost impossible to get stains out of the material. What would you suggest to use to get stains out? It is a light green color so stains are very noticeable.

      Hi Tami! That’s a tough situation. One method would be trying to clean the stains with a mild dish soap. For spot treating stubborn stains, we recommend mixing a small amount of Activewear Detergent powder in a bowl with some water to create a paste. Apply that paste to the stain and let it sit for 15 minutes before washing the area with cold water.

      If possible, first try testing this method on a stain in an inconspicuous area to ensure the detergent doesn’t affect the color of your hoodie. Good luck!
