Washing Rehband Warm Pants

Not the most exciting question.
I recently purchased a pair of the rehband warm pants. The blue shorts that seem popular with strength competitors. Looking for advice on how to wash them.

I wash them with the rest of my clothes. Nothing special.

If they are neoprene like the knee sleeves then follow directions for washing a wetsuit.

Should also get some detergent called “sport wash” that is made for materials like this.

Wash cold, air dry in the sun.

They are the same. I’ve washed in cold so far, and air dry. Will try to sun dry idea
Thank you
