I've slowly been replacing all of my underwear with 2UNDR Swing Shift.
I've got about 20 pairs now, and they are amazing. I don't like wearing anything else.

They're more expensive than Saxx but last a lot longer and are way more comfortable. I have 3 pairs of Saxx and would rather wear the 2UNDR's any day.
