Reduces the chafing, blisters and saddle sores that occur with endurance sports. Protects your skin by forming a thin, silky llow-friction layer between skin and clothes as well as an effective moisture barrier to protect against sweat and water. Long lasting so reduces the need for inconvenient re-application. Most effective when used prior to activity, but also soothing to skin when used after endurance activites. Has natural Australian Tea Tree oil which has anti-septic and anti-fungal action to reduce the possibility of infection.
