I recently purchased 12 pairs of your Premium X Temp underwear expecting them to high quality products. On the positive side the material used is extremely comfortable. My complaint is with the waist band. All 12 of them have a waist band that will not stay upright, it keeps flipping over in half. I have never had this issue with any other underwear. Taking into consideration that these underwear retail for $20 for a pair of 4, I paid $80 for underwear that is subpar. I feel like the Hanes company robbed me blind as I now have 12 pairs of brand new underwear that is uncomfortable to wear. :-( I would like all 12 pairs to be replaced by the company.
