Nipple chafing and bleeding is a common problem for men when it comes to exercise. Persistent friction between the nipples and the shirt fabric while playing sport or running can cause the skin around the nipples to break and bleed.

Given that this is a highly sensitive part of the body, nipple chafing is not only uncomfortable and painful but it can also take a long time to properly heal.

For women, nipple chafing is less of a concern as sports bras can sometimes provide the necessary protection. However, women have other concerns.

Sudden temperature changes and the sensitivity of the nipples can cause them to protrude and result in embarrassing stares from men.

Certain clothing will highlight erect nipples, making it difficult to wear certain fabrics and designs.
