This hat is labeled "packable" and "crushable".  If your definition is that it can be crushed, then it is.  If you expect it to return to original shape then it is not. Amazon crushed this hat to ship it in a small box and it would not return to original shape until I steamed it.  Otherwise I like the hat, but I have no intention of ever putting it in a suitcase.  I can't really fault Amazon because the hat is clearly labeled crushable.  After I put it back in shape it really looks good, fits perfectly and is a good purchase.
