Activewear Fabric Care Guide
Pick a fabric to see its wash temperature, dry method, and the do’s and don’ts that keep it performing longer.
Spandex / Elastane care guide
Do
- Turn garments inside out before washing to reduce fiber abrasion
- Wash with similar colors on a gentle cycle
- Reshape and lay flat while damp to preserve stretch recovery
Don’t
- Don't use hot water — heat breaks down elastane's stretch over time
- Don't tumble dry on high heat — it's the fastest way to kill compression
- Don't use chlorine bleach — it degrades the elastane fibers
General garment-care guidance for this fiber type — always defer to the specific care label sewn into your garment, since finishes and fabric blends vary by brand.
General rules across every activewear fabric
A few habits apply almost regardless of fiber: wash activewear inside out to reduce abrasion on printed or bonded panels, avoid fabric softener on anything built to wick moisture, skip chlorine bleach on anything containing elastane, and rinse sweaty gear promptly rather than letting it sit balled up in a gym bag, which is what really sets in odor over time.
These are general textile-care conventions, not a substitute for the specific care label sewn into a garment — finishes, treatments, and exact fiber blends vary by brand and by piece.
Frequently Asked Questions
Why does activewear need different care than regular clothes?
Most activewear relies on stretch (spandex/elastane) and moisture-wicking synthetics (polyester, nylon) to do their job. Both are more sensitive to heat and to fabric softener than an ordinary cotton t-shirt — heat breaks down elastane's stretch over time, and fabric softener coats synthetic fibers in a way that blocks the wicking action that moves sweat away from your skin.
Why is fabric softener specifically bad for workout gear?
Fabric softener works by leaving a thin waxy coating on fibers. On wicking synthetics, that coating fills the tiny channels the fabric uses to pull moisture away from your skin, which is why gear that's been softened repeatedly starts to feel clammy and smell worse even right after washing.
Is cold water really necessary, or is that overly cautious?
For anything with spandex or elastane, yes — heat is the main thing that degrades stretch recovery over repeated washes. Polyester and nylon are a bit more heat-tolerant, but sticking to cold-to-warm water across the board is a simple habit that protects every piece in a mixed-fabric wash load.
Can I put activewear in the dryer at all?
Low heat is generally fine for polyester and nylon; spandex/elastane pieces do best air-dried or on the lowest, no-heat setting to protect their stretch. Merino wool should never go in the dryer — lay it flat instead, since dryer heat and tumbling can felt and shrink wool fibers.
What if my garment is a blend of several of these fibers?
Default to the most sensitive fiber in the blend — if a legging is polyester/spandex, follow the spandex guidance (cold wash, low/no heat); if a top blends cotton and elastane, favor cold water and air drying over the cotton-blend defaults. When in doubt, the garment's own care label is the final word.
General guidance only, not a substitute for your garment’s own care label — always defer to it when the two disagree.
