Machine wash cold, inside out with like colours. Only use non-chlorine bleach when needed. Do not use silicone softeners. Tumble dry and warm iron when necessary.
These are my everyday pants now. They handle biking and rock climbing amazingly since they stretch and the gusset being reinforced shows no signs of weakness! Love these!
I now have several pairs of these in various colours. I think they are the most comfortable pants you can own.
