| Sawyer®'s Bonding Base Sun Block can last all day even under intense conditions such as high altitude, high and low humidity, high temperature, extreme UV radiation and heavy perspiration from physical exertion. These sunscreens also resist physical abrasions such as clothing, water and sand. When clothing is put on an appropriate amount of time after sunscreen application, an adequate level of protection remains if the clothing is then removed in sunlight. |
