We have never tried the Woolx merino tops but gave it a try.  My husband wore this shirt 6 days in a row to exercise - got drenched with sweat each time.  Got home, put it on a hanger and let it air dry.  To this minute - the shirt looks great and has absolutely no smell at all.  It's really amazing.  Woolx has the SOFTEST merino wool I have tried recently.  Super pricing, super soft - and looking forward to a lot of use in the future
