@wbmshm78 Thanks for reaching out!
If you would like to make a return via mail, you can find all the information you need on our Return Instructions page. It is good to note that we are working hard to re-open stores, so you may be able to make a return in store soon. The best way to find the information about which stores are open is to visit your local REI store page, as we will update those first.
Hopefully this helps!
