Bought a 10 pack out the gate, they are absolutely amazing. I’m actually throwing out all of my current draws out and buying another pack ASAP... I don’t have the drive to be a keystroker in a nice air conditioned office, I’m a tradesman in the IBEW and do we get hot and sweat. I’ve never had this much breathability/ movement from an underwear garment, very light material barely notice your wearing anything....... my only gripe is that you can’t mix colors. But the quality of the product is on 15
