It's a quality product and live up against many many washing...we're going through potty training right now with these underwear.  My daughter is on the skinny side (for a baseline, she's 3 but 2T pants by old navy falls right off of her waist) so even with the 2T size we still have to pre shrink it (i.e. wash in hot water and dry in high heat).  Still after all that the underwear is still nice and soft.
