Nyko, a gaming gear company based out of Los Angeles, have developed a new attachment for Xbox One and PS4 controllers that help fight sweaty hands.
If this natural bodily occurrence happens to you, and you don't like it, this may be worth looking into.
Chris Arbogast, Nyko's Director of Sales and marketing, states "[c]ontrollers can become slipping and hard to use during extended gameplay sessions due to sweat, [w]e've solved that problem by bringing our console Intercooler technology to controllers, delivering airflow to the player's palms with a discreet cooling fan."
