How to Machine Wash Your Activewear Without Ruining It

Quick Answer

Machine wash your activewear in cold water on a gentle cycle, use a mild detergent without fabric softener, and always air dry. Turn items inside out, fasten hooks and zippers, and skip the dryer to preserve elasticity and moisture-wicking performance.

Your workout clothes take a beating—sweat, stretching, and constant wear. But how you wash them matters just as much as how you train. One wrong cycle can leave your favorite leggings saggy, your sports bra stretched out, or your tank top smelling even after a wash.

The good news: you don’t need special equipment or expensive detergents. With a few simple habits, you can keep your activewear looking and performing like new. Here’s your step-by-step guide to machine washing activewear the right way.

Step 1: Check the Care Label

Before anything else, look at the care label on each piece. It tells you the fabric blend and the safest washing temperature. For example, the Eon Chakra Crossover pocket leggings are made from 82% polyester and 18% spandex, which means they need a cold, gentle cycle. Hot water can break down the spandex and ruin the stretch.

If a label says “hand wash only,” don’t ignore it. But for most machine-washable activewear, a cold, gentle cycle is a safe bet. When in doubt, go colder and gentler—it’s easier to rewash than to fix a shrunken or misshapen piece.

• Checkpoint: If the label is missing, assume cold water and a delicate cycle.

Step 2: Turn Inside Out and Fasten Everything

Turn your activewear inside out before washing. This protects the outer surface from friction and pilling, and it helps preserve the color. Fasten any hooks, zippers, or Velcro closures—like the ones on sports bras or jackets—so they don’t snag other items.

For bras with padding, remove the pads if you can, or use a mesh laundry bag. This keeps the pads from shifting or tearing in the wash. The same goes for delicate straps and trims.

• Checkpoint: Mesh bags are your best friend for small or delicate items.

Step 3: Use Cold Water and a Gentle Cycle

Set your machine to cold water and the gentle or delicate cycle. Cold water is essential for activewear—it prevents shrinking, fading, and the breakdown of elastane. The gentle cycle reduces friction, which helps maintain the fabric’s four-way stretch, like the kind you find in the Astro Sol Sports bra.

If your machine has a spin cycle, use the lowest setting. High-speed spinning can stretch out your clothes and cause wrinkles that are hard to remove. A low spin leaves your activewear slightly damp but in better shape.

• Checkpoint: Cold water + gentle cycle = the safest combo for most activewear.

Step 4: Choose a Mild Detergent, Skip the Fabric Softener

Use a mild, liquid detergent that’s free of bleach and optical brighteners. These chemicals can break down the fabric and reduce moisture-wicking properties. Fabric softener is a big no—it coats the fibers and clogs the pores, making your clothes less breathable and less effective at wicking sweat.

If your activewear smells even after washing, it might be due to bacteria buildup. Add a half-cup of white vinegar to the rinse cycle—it’s a natural deodorizer that won’t damage the fabric. Avoid bleach, even on whites, as it can weaken the fibers.

• Checkpoint: No fabric softener, ever. Vinegar is a great natural alternative.

Step 5: Air Dry, Never Tumble Dry

The dryer is the enemy of activewear. High heat can melt synthetic fibers, break down elastic, and cause shrinkage. Always air dry your clothes—hang them on a line or lay them flat on a clean towel. Hanging is fine for most items, but for heavy pieces like leggings, lay flat to avoid stretching.

If you must use a dryer, use the lowest heat setting and remove the items while they’re still slightly damp. But honestly, air drying is the best way to extend the life of your workout clothes. It takes a little longer, but your favorite pieces will last much longer.

• Checkpoint: Air drying is the single best thing you can do for your activewear.

Quick Care Checklist

1. Check the label: Look for fabric content and washing instructions. Adjust your cycle accordingly. When in doubt, go cold and gentle.
2. Prep your clothes: Turn inside out, fasten hooks and zippers, and use a mesh bag for small items. Protects fabric and prevents snags.
3. Wash with care: Use cold water, gentle cycle, and a mild detergent. Skip fabric softener. Preserves stretch and moisture-wicking performance.
4. Dry the right way: Air dry flat or on a line. Avoid the dryer to prevent shrinkage and damage. Air drying is the simplest way to extend the life of your activewear.

Product Facts: What to Look For

• Eon Chakra Crossover pocket leggings: 82% polyester, 18% spandex, UPF 50+, peach-skin four-way stretch fabric, high-waisted with double-layered waistband. The spandex content means cold water and gentle cycles are essential to maintain stretch. The double-layered waistband also holds its shape better if you avoid high heat.
• Astro Sol Sports bra: Moisture-wicking fabric with support material in shoulder straps, double layer front, and wide elastic band. 82% polyester, 18% spandex. The moisture-wicking technology only works if the fabric stays clean and free of fabric softener buildup. Washing inside out and air drying keeps the straps and elastic from stretching out.
• Rise of Zen Unisex Tank Top: 100% combed ringspun cotton (tri-blend options available), 4.2 oz/yd², side-seamed. Cotton is more durable than synthetic blends but can shrink in hot water. Wash in cold and air dry to keep the fit true to size.

Caring for your activewear doesn’t have to be complicated. With these simple steps—checking the label, prepping your clothes, washing in cold water, and air drying—you can keep your favorite pieces looking and performing great for years. So next time you finish a workout, you’ll know exactly how to wash your activewear without ruining it.
