Comfy stretchy breathable fabric. Sometimes I have to look down to remind myself that I’m still wearing pants and even then, it adds SO much confidence to feeling pantsless. I’ve had to start wearing disguises when leaving home as I am starting to become something of a celebrity with these. I wear these to work, to the gym, to shower, to sleep, to swim, to wrestle giraffes and more. I will be requesting to be buried in these so I can rest eternally in the comfort of this magic fabric. Do yourself a favor and order 7 of these so you have a full week’s worth.
