Investing in premium athletic apparel is an investment in your fitness journey. When you purchase high-performance gear, you expect it to perform flawlessly session after session. But to get the absolute most out of your gear, you need to know how to properly maintain it.
Protect your investment. Learn exactly how to wash sportswear and maintain your high-tech fabrics for peak performance. This ultimate activewear care guide will teach you the golden rules to make gear last longer and keep it smelling fresh.
Why Proper Care is Crucial for Tech Sportswear
You wouldn't wash a silk suit the same way you wash a cotton t-shirt. The same logic applies to modern athletic apparel. Tech sportswear is engineered with specialized fibers and coatings that require specific attention.
Protecting Heat-Reflective Coatings (Silver-HeatREG®)
The secret behind the intense thermal effect of our gear is the advanced fabric technology. For instance, our patented Silver-HeatREG® technology relies on a delicate heat-reflective layer inside the garment.
Harsh chemicals, aggressive machine cycles, or extreme heat can break down this coating. If the coating degrades, the suit loses its ability to trap heat effectively. Proper care ensures this technology remains intact, workout after workout.
Preventing Bacteria and Odor Buildup
Intense workouts mean intense sweat. When sweat gets trapped in the fibers of your clothing, it creates an ideal breeding ground for bacteria. This bacteria is what causes that stubborn, lingering gym odor.
Correctly washing your gear doesn't just clean the surface; it neutralizes these bacteria, ensuring your clothes remain hygienic, skin-friendly, and odor-free for your next session.
How to Wash Sportswear: The Golden Rules
When it comes to high-performance activewear, especially items with technical linings like sauna suits, less is often more. Follow these golden rules to protect your apparel.
Rule #1: Always Hand Wash in Cold Water
This is the most critical rule for preserving tech fabrics. The agitation and friction of a washing machine can cause micro-tears in the heat-reflective lining.
Always hand wash your gear. Fill a basin or sink with cold water. Cold water is essential because hot water can damage elasticity and compromise waterproof or heat-reflective coatings. Gently agitate the garment in the cold water.
Rule #2: Choose a Mild Detergent
Standard laundry detergents are often packed with harsh chemicals, brighteners, and heavy fragrances that can strip away the specialized properties of your activewear.
Opt for a mild, gentle detergent. You only need a small amount. Avoid scrubbing the fabric vigorously against itself, especially on the inner lining. Gently massage the soapy water through the material.
Rule #3: Skip the Fabric Softeners and Bleach
Never use fabric softeners or bleach on your gym clothes. Bleach is highly corrosive and will immediately damage the fibers and coatings of your gear.
Fabric softeners work by leaving a waxy residue on clothes to make them feel soft. However, on activewear, this residue clogs the technical pores, completely ruining the fabric's breathability and moisture-wicking capabilities.

Drying and Storing Your Gear Correctly
Washing is only half the battle. How you dry and store your activewear is equally important for its longevity.
Flat Dry in the Shade: Avoiding Direct Sunlight
UV rays from direct sunlight can break down synthetic fibers and cause colors to fade prematurely. It can also dry out and crack technical inner linings.
After washing and gently squeezing out excess water (do not wring or twist the fabric tightly), lay your gear flat to dry in a well-ventilated, shaded area.
Do Not Iron or Tumble Dry
Heat is the enemy of performance fabrics. Never put your sauna suits, leggings, or sports bras in a tumble dryer. The intense heat will destroy the elastic fibers (like spandex or elastane) and melt heat-reflective coatings.
Similarly, never use an iron. The direct heat will instantly damage the fabric. Air drying is the only safe method.
Storing to Maintain Shape and Elasticity
Make sure your gear is 100% dry before storing it to prevent mildew. Hang your jackets and tops on smooth hangers to maintain their shape.
Avoid tightly folding or compressing items with technical coatings, as sharp creases over a long period can weaken the lining.
Specific Care for Different Activewear Pieces
While the golden rules apply generally, different pieces require slight variations in care.
Cleaning Your Sauna Suit Jackets and Pants
For your sauna suits, after a light workout, you can often just turn the suit inside out and wipe down the silver lining with a damp cloth or a gentle anti-bacterial wipe, then hang it in a cool place to air out. For a deeper clean, follow the cold-water hand-wash routine.
Caring for Sports Bras, Leggings, and Inner Linings
These items sit closest to your skin and absorb the most body oils. Wash them promptly after your workout to prevent odors from setting in. Since they rely heavily on elasticity for support and compression, keeping them away from heat (hot water and dryers) is absolutely paramount.
Treat Your Gear Right, and It Will Reward You
By following this activewear care guide, you are protecting your investment. Treat your gear with respect, and it will continue to provide the performance, support, and thermal efficiency you need to crush your goals.

Common Questions About Washing Activewear
Can I ever put my sauna suit in the washing machine?
Standard sauna suits must be hand-washed to protect the inner coating. However, technological advancements have allowed us to create specific lines that are machine washable. Always check the care label on your specific product!
Tech Innovation:
Is it okay to soak my workout clothes for a long time?
No, do not soak your activewear for a long period. Prolonged soaking can break down the fibers and loosen the adhesives used in technical garments. A quick 5-10 minute soak during hand washing is sufficient.
How do I get tough sweat smells out of my gear?
If a mild detergent isn't enough, you can add half a cup of white vinegar to your cold-water basin. Vinegar is a natural deodorizer and antibacterial agent that helps strip away built-up sweat and odor without damaging the fabric.
Can I dry clean my Hotsuit apparel?
Absolutely not. The harsh chemical solvents used in the dry-cleaning process will severely damage the synthetic fibers, elastics, and thermal coatings of your activewear.Shop the Hotsuit collection knowing your investment is built to last.
