I know the cotton can carry germs and bateria, but man, the 10th Planet spatz really do offer unparalleled gripping with the legs. I find my Kimurawear and Scramble spatz are slippery, and thos meekatsu octopus spatz are dipping your legs in baby oil.
Not bad for yanking free of leg attacks, but it puts your leg grips at a slippery disadvantage.
