These came from China. They are the same size as my 8's. I ordered this pack and a separate Fruit of the Loom pack - both size 9. This one has a much stiffer waistband too. No comparison to the other 5 pack Microfiber size 9. The other pack is significantly larger in size. https://www.amazon.com/dp/B078C7Z935/ref=cm_cr_ryp_prd_ttl_sol_1  The link should take you to the good product - not the Chinese product.
These are equivalent to a size 8 not a 9. Elastic waistband is not that stretchy.
