How should compression garments be washed to keep their support?

Main answer

Wash compression garments in cool water, inside out in a mesh bag, with a mild detergent and no softener or bleach, and air dry them flat. Their support comes from high-elastane fabric and elastic bands, and heat, chemicals and rough handling weaken these fibres faster than anything else. Replace them once they stop holding their shape, because worn compression garments no longer do their job.

What provides compression

Compression comes from a high share of elastane in a tightly knitted fabric, and from the grip and tension of bands and seams. Over time stretch, heat and sweat residues reduce recovery. Because the garment is worn close to skin, it also holds sweat and oils, so regular washing is needed, and gentle washing is what keeps support.

Washing steps

Rinse soon after use when possible, then wash inside out in a mesh bag with similar items. Use cool or warm water and a small amount of mild detergent. Avoid chlorine bleach and fabric softener, since both can damage elastane or leave a film. Close hooks and zips and avoid washing with abrasive items.

Drying

Air dry flat or hang in the shade, away from direct heat and sun. Avoid the dryer unless the label allows low heat. Do not wring. Do not iron over printed areas or elastic. Allow the garment to dry fully before storing, since damp items can hold odour and mildew.

Storing and rotating

Store compression garments flat or loosely folded in a drawer, away from heat, and avoid keeping them tightly stretched on a hook. Rotating several pieces gives the elastic time to recover between wears.

Fit and replacement

Compression garments lose recovery with use, so replace them when they no longer hold their shape or stay in place. Wearing two or three in rotation extends life. Under the FTC rule, apparel must carry care instructions, so follow the label. See performance and compression guide.
