Choose the NEW Sport+Fashion Full Size (1.25") if your primary use will be for fashion or to help conceal the nips under clothing.
For Endurance Athletics and Nipple Chafing Prevention:
Place a clean penny on one of your bare nipples. Does it cover most of the areola? If so, choose Size Regular (fits most).
The NipEAZE should not be larger than the outside diameter of the areola unless your primary objective is to help conceal your nipples.
Regular – 3/4” – Fits most (about the size of a US Penny)
Extra – 1” – For larger nipples (slightly larger than a US Quarter)
Endurance Athletes and Runners: Why Measure?
For the adhesive to be most effective against moisture & friction, NipEAZE should fit so that it comes in contact with the areola only; not the skin around it. If your measurement is between two sizes, choose the smaller size.
