Measure at the Natural Waist
Wrap a tape measure around your waist, where the waistband sits.
Between Sizes?
Size up for a relaxed feel. Size down for a more fitted, performance look.
No Underwear Needed
Our Aqua Liner (compression inner) replaces underwear — designed for water, comfort, and support.
Get It Right the First Time
Find Your Natural Waist
Stand relaxed and wrap the tape measure around your wiast where you normally wear jeans / pants / shorts. This is where the waistband sits.
