This is best sun protection for a mountain man on the face of the planet. I live with five-o’clock shadow and sunscreen creams just don’t rub in well, they make me look like a grey-haired ghost. Keihl’s Cross-Terrain applies quick and clear and comes in a burly hockey puck-style container that I can leave in my pack or pocket to get smashed around during a tumble or a long travel and won’t leak or burst open make a mess. Its viscosity provides protection from extreme winds and is a worthy lip balm, so I don’t have to carry two items. In a pinch, after weather forced a retreat from Half Dome, I used it to lubricate some extremely chaffed body parts and found some clutch relief. SPF 50 means I put it on once, even at the highest altitudes, during the longest surf sessions and in the most extreme elements.
