Activewear is no longer just gym clothes. It’s our yoga uniform, running outfit, coffee-run style, and sometimes even our work-from-home fashion. But while we love wearing it everywhere, not everyone knows how to wash activewear properly so it stays fresh, stretchy, and supportive for a long time.
If you’ve ever wondered why your compression leggings suddenly feel loose, why your sports bra smells weird even after washing, or why your favorite workout top looks faded too fast—don’t worry, we're gonna help you out.
Activewear needs special care, and once you understand how to treat it right, your clothes will last longer and perform better. Let’s learn it further here!
Why Washing Activewear Is Important
You might think, “It’s just sweat, I’ll wash it later.” But here’s the thing—activewear is designed to absorb moisture, and that makes it the perfect place for bacteria to grow.
1. Sweat + Bacteria = Bad Smell
When you work out, your body releases sweat, oils, and dead skin cells. These get trapped inside the fabric fibers. If you don’t wash your activewear properly, bacteria build up and cause that stubborn smell that doesn’t go away even after washing.
That’s why some gym clothes still smell funky straight out of the laundry.
2. Keeps Fabric Performing Well
Activewear is made with special materials like polyester, spandex, and nylon. These fabrics are designed to:
- Stretch and recover
- Wick away sweat
- Dry quickly
- Stay breathable
But improper washing can damage these properties. Hot water, harsh detergent, and rough drying can break down the fibers, making your clothes lose elasticity and comfort.
3. Protects Your Skin
Dirty activewear can cause skin irritation, breakouts, and even fungal infections—especially in areas that stay damp like underarms and inner thighs. Washing workout clothes properly keeps your skin healthy and comfortable.
Special Washing Instructions for Activewear
If you want your workout clothes to last longer and still feel amazing every time you wear them, following the right washing method is a must. Activewear is made from special performance fabrics that need gentle care to stay stretchy, breathable, and odor-free.
Here are some simple but powerful washing tips that will help keep your favorite gym outfits looking and feeling like new.
1. Water Temperature: Cool Is King
One of the most important rules in how to wash activewear is to avoid hot water. High temperatures can damage the elastic fibers that give your leggings their stretch and your sports bra its support.
The best choice is always cold or cool water, ideally at 30°C or below. Cold water helps prevent fabric from stretching out, protects elastic fibers, keeps colors from fading, and reduces the risk of shrinkage.
On the other hand, hot water can slowly break down spandex and elastic, making leggings feel loose and sports bras lose their shape and support over time.
2. Detergent: Less Is More
Not all detergents are friendly to activewear. Regular heavy-duty detergent may seem powerful, but it often leaves residue behind. This residue can trap odors and block the fabric’s ability to breathe and wick away sweat.
For best results, use a mild detergent, a sportswear-specific detergent, or a liquid detergent instead of powder. Liquid detergent dissolves more easily and rinses out better, leaving less buildup in the fabric.
Try to avoid fabric softener, bleach, and strong chemical detergents. Fabric softener might make clothes feel soft at first, but it actually coats the fibers and ruins their sweat-wicking ability. Over time, this makes your activewear feel heavier, smell worse, and perform poorly during workouts.
3. Turn Clothes Inside Out
This small habit makes a surprisingly big difference. Before putting your activewear into the washing machine, turn everything inside out.
Washing activewear inside out helps clean sweat and bacteria more effectively because those are usually trapped on the inside of the fabric. It also protects the outer surface from friction, which helps preserve the color, texture, and overall look of your clothes.
As a bonus, this method also helps remove deodorant stains and body oils that build up around the underarm and neckline areas.
4. Separate from Regular Laundry
Activewear deserves its own wash cycle whenever possible. Mixing it with heavy items like jeans, towels, or jackets can damage the fabric and reduce its lifespan.
Jeans and towels create friction that can weaken and stretch performance fabrics. Cotton items also shed lint, which sticks easily to synthetic fibers and makes your clothes look worn out faster. Zippers, buttons, and rough seams from other garments can also cause snags and pulls in delicate activewear.
If you must mix loads, wash your activewear only with other lightweight fabrics to keep everything safe and in great condition.
When to Replace Activewear
No matter how well you care for it, activewear won’t last forever. Even the best workout clothes go through a lot—stretching, sweating, washing, and drying again and again.
Knowing when to replace your activewear is important because worn-out pieces don’t just look bad, they can affect your comfort, performance, and confidence during workouts.
Here are the signs it’s time to say goodbye and upgrade your gym wardrobe.
1. Loss of Elasticity
If your leggings keep sliding down or your sports bra no longer supports you properly, that’s a clear sign the elastic is worn out. Elastic fibers naturally weaken over time, especially with frequent washing and heavy use.
When elasticity is gone, you’ll notice less comfort, reduced performance, and a higher risk of wardrobe malfunctions while exercising. If you’re constantly adjusting your leggings or worrying about your top during a workout, it’s definitely time for a replacement.
2. Fabric Feels Thin or Transparent
If your leggings become see-through when you squat or stretch, that’s your fabric telling you it’s reached the end of its life. Thinning fabric means the fibers have weakened and can no longer provide proper coverage or durability.
3. Lingering Odor That Won’t Go Away
Have you tried special detergent, vinegar soaks, and careful washing but your activewear still smells bad? Unfortunately, that means bacteria have permanently embedded themselves deep into the fabric fibers.
Once odor becomes impossible to remove, the fabric is no longer hygienic or comfortable to wear. At that point, replacing it is the healthiest choice for both your skin and your confidence.
4. Visible Damage
Always keep an eye out for physical signs of wear and tear, such as loose seams, pilling, small holes, or fraying straps. These might seem minor at first, but they can quickly get worse and affect how your activewear fits and performs.
Visible damage doesn’t just change how your clothes look, but also weakens their structure and support, making them less reliable for workouts.
5. Reduced Comfort
If your once-favorite leggings now feel itchy, stiff, or uncomfortable against your skin, the fabric coating may be worn off. Over time, sweat, washing, and friction can break down the soft protective layer that makes activewear feel smooth and breathable.
When comfort is gone, motivation often follows. After all, it’s hard to enjoy a workout when your clothes don’t feel good anymore.
