I never knew there was such a problem while running until I started doing endurance long runs. Chafe?!?! You'll chafe in places where you'd never imagine. TMI, I know... but as a guy, if you're a fan of The Office, Jim had his nipples bleed. That's because the texture of your shirt moving up and down while running will make them sensitive. Also, it's great for preventing blisters, chafing from your shirt, or fuel belt. So.... for preventive action, use this!

This helps prevent blisters, chafing, dry skin, cracked skin and rash. Use it everywhere - for hands, feet, upper body, inner thighs, under arms, shoulders and chest (nipples).
