How To Wash Gym Shorts Without Losing Stretch Or Liner Shape

Why Heat Is The Enemy Of Stretch Recovery

Elastane (spandex) fibres, the component responsible for a fabric's stretch-and-recover ability, degrade faster under repeated heat exposure. High-heat washing or drying accelerates the gradual loss of elastic recovery that all stretch fabric experiences over time - the same mechanism covered in our 4-way stretch fabric explainer.

Why Fabric Softener Is Also A Problem

Moisture-wicking fabric moves sweat via capillary channels between fibres. Fabric softener coats those fibres with a residue that blocks this wicking action, which is exactly the opposite of what you want from a performance short. Skip softener entirely for any moisture-wicking gym apparel.

The Correct Wash Routine

1. Cold water, 30°C maximum.
2. Gentle cycle.
3. No fabric softener.
4. Tumble dry low or air dry.

Caring For The Built-In Liner Specifically

The mesh liner sewn into the waistband is thinner than the outer shell and benefits from the same cold-wash approach, but pay attention to it separately when checking for wear - liner elastic can fatigue at a different rate than the outer shorts fabric since it experiences direct skin contact and different stress patterns.
