Our SuperFit fabric is the best present you can buy your junk. Made of a very special, microfiber polyamide it feels a bit like a basketball jersey. It has 4-way stretch and is form-fitting, but does not constrict at all. It’s also cool to the touch, ultra breathable, moisture-wicking, quick-drying, flat-stitched, and generally amazing. Get ready to replace your entire underwear drawer. Seriously.
