SAXX underwear is sized by waist measurement and features their signature BallPark Pouch™ — a built-in hammock-style support system designed to keep everything in place all day. Getting the right size ensures the pouch works as intended.
How to Measure
Waist: Measure around your natural waistline, about 1" above your navel, keeping the tape snug but comfortable. This is the measurement SAXX uses for sizing — not your pants waist size.
⚠️ Heads up on sizing: SAXX underwear tends to run one size larger than most underwear brands. If you’re between sizes or typically wear a medium in other brands, you may find a SAXX Small fits perfectly. When in doubt, ask us — we’re happy to help.

Style Guide
Boxer Brief: Mid-thigh length. The most popular SAXX style — great for everyday wear and active use. Keeps everything secure without riding up.
Trunk: Shorter leg than a boxer brief, sits at the upper thigh. Great for slim-fit pants where you don’t want visible lines.
Brief: Minimal coverage, maximum freedom of movement. Ideal for warmer weather or under fitted trousers.
Boxer: Loose fit with a longer leg. Maximum airflow and comfort for lounging or sleeping.
Long Leg Boxer Brief: Extended leg coverage, ideal for preventing thigh chafing during athletic activity or travel.
About the BallPark Pouch™
Every SAXX style features their patented BallPark Pouch™ — a mesh-lined hammock that cradles and separates, eliminating friction and keeping you comfortable all day. For the pouch to work correctly, the waistband should sit at your natural waist without digging in or sagging. If the waistband rolls or the pouch feels tight, size up.
Caring for Your SAXX
Machine wash cold on the gentle cycle with like colors. Tumble dry low. Non-chlorine bleach only. Iron on low if needed. To make them last longer, use a mild detergent and line dry instead of machine drying.
