I purchased two sets of these boxer shorts for my son. After a few washings, the elastic waistband on some of the shorts (4 out of 10) deteriorated (became brittle and was no longer elastic) and I've had to discard the shorts, which was a shame since the material was such good quality. I was about to order more shorts, but decided to email Lucky & Me to notify them of the quality issue. They sent me a brand new set as a replacement FREE OF CHARGE and told me to let them know if I run into the same issues (and to send pictures) so that they can follow up with their partner factory. If I could give 6 stars for this product for their excellent customer service, I would. Thank you Lucky & Me! :)
