When you shop for a jockstrap, it's important that you choose the right size jockstrap, especially if the jockstrap is to be worn for sports, the gym or for any other athletic activity.
Our Jockstrap sizing recommendations are slightly different depending on their purpose but some basic rules that apply for both: Know your actual waist size and follow our sizing recommendations.
KNOW YOUR WAIST SIZE
Your waist size is not your jeans size.
Do not, and I repeat, do not assume your actual waist size is the size of the last pair of Levi Jeans you bought. Some jeans fit low on your hips and other high on your waist plus many clothing designers are now incorporating vanity sizing - essentially lying about the actual waist size to make you feel good. Measure your waist size to be certain.
To determine your actual waist size: go to the dollar store and get yourself a soft fabric measuring tape and measure around your actual waist. You can also get a piece of string: holding one end, wrap the string around your waist until it meets back up at the start, and mark it or cut it. Lie the string along a ruler to determine the size jockstrap you need.
Jockstraps for sports provide support and protection, they are designed to keep your genitals in place when you run or jog and in the case of a hard cup supporter, they protect your genitals from impact. To provide this support and protection, sizing is of utmost importance. The waistband should be snug, the leg straps taut which in turn pulls the pouch down to keep your penis and testicles from moving around. We recommend going with the manufacturer's recommended sizing. If you're in between sizes, then for sports you're better off going down a size. If you're planning on wearing your sports jock as regular underwear, consider going up a size for comfort. Elastics are forgiving.
