So awhile back I picked up some plain old white socks at Costco. When most people think of white cotton socks or undershirts they normally by Hanes. Well let me tell you whatever Costco uses is top notch. Hanes feel nice and thick for about 3-4 washes then they loose their thickness and start to wear out. Not Costco, they always have a nice thick feel to them and after many washes still stay thick. I recently picked up some white cotton undershirts as well and low and behold the same effect. Won't ever by Hanes again.
