i wash in cold water... in the washing machine.. with no dye... no perfume.... a "free" detergent... as per pearl izumi... do NOT use woolite.. it's actually very harsh for your delicate clothes and not good for lycra types (again.. this is per PI! i wrote them about my deteriorating leg warmers.. and when i mentioned woolite.. they said NO NO NO!)

i hang them to dry.... no dryer!
