It's either a 2x2 ribbing or you could knit something like a Fisherman's rib
with very thick yarn and large needles. You don't really need a pattern, just determine how wide you want it and how many sts per inch you get in pattern and cast on until it's long enough. You probably would need about 150-200 yards.
For a guy I would suggest about 8" wide, not the 12" or more as shown in the pictures.
