Now that I have given you some more insight on what to do if your sweatpants do shrink and How to Wash Your Sweatpants properly let me guide you through the specifics to not allowing your sweatpants to shrink ever again.

Hang Dry

Putting your sweatpants up to hang dry/air dry is your safest bet when preventing any shrinkage. To do this properly, wash the sweatpants in cold water and let the washing machine go through the whole cycle. This will allow the washer to complete the spin-cycle, eliminating excess water.

If the weather is above 15c/59f, you can hang your sweatpants and clothing outside to dry. The combination of the sun’s rays and the warm breeze will quickly dry your garments. 

Options to hang your sweatpants on:

  • Drying rack
  • Towel rack
  • Shower curtain bar
  • Back of chair
  • Clothing line

Tumble Dry Low
