Should leggings go in the dryer?
Key takeaways
- The dryer is the single biggest cause of leggings losing their shape.
- The last part of a hot cycle does most of the damage.
- Air drying flat avoids stretching the waistband under the weight of wet fabric.
- A cold wash and air dry restores most temporary stretch.
What the heat does
Elastane recovers because of elastic segments in the polymer. Heat degrades those segments, and once they are gone the fabric still stretches but no longer pulls back. That is what a pair of leggings that has gone permanently baggy actually is.
If you have to use a dryer
Use the lowest heat setting available and remove the garment while it is still slightly damp. The final minutes of a hot cycle, when the fabric is dry and still tumbling in heat, do a disproportionate share of the damage.
Air drying properly
Dry flat or over a rail. Hanging heavy wet knits by the waistband lets gravity stretch the band, which is the part of the garment you least want stretched. Keep dark colours out of direct sun, which fades them.
What to do with a pair that has gone baggy
Wash cold and air dry. That restores most temporary stretch, which is why leggings feel like new again after washing. If they stay loose afterwards, the elastane has lost recovery permanently and no treatment brings it back.

Frequently asked questions
- Can you tumble dry leggings?
- You can, but heat degrades the elastane that makes them return to shape. Use the lowest setting and remove them slightly damp, or air dry.
- Does the dryer shrink leggings?
- The base fibre can shrink slightly, but the more important effect is that heat damages the elastane, so the pair ends up both tighter in places and baggier in others.
- How do I dry them quickly without a dryer?
- Roll them in a towel and press to remove water, then lay them flat on a rack. Do not hang them by the waistband while heavy with water.
