Not to worry. NewGrips put a protective barrier between you and those unwanted germs. Both hand pads and wrist bands are washable with liquid soap. Air dry or pat dry with a towel. NewGrips seem to wick-away sweat.
Hands stay cool and fresh.
The fingerless design is the reason. As soon as you release your hand from a bar the pad falls away from your palms. This allows fresh air to cool your hands. Hot, sweaty, smelly hands are a thing of the past. Anyone who has difficulty gripping, whether from age, arthritis, injury, tendonitis, bad back, osteoporosis, etc. will get better workouts using NewGrip.
