FAQ
How do I know what size to choose?
A size chart for the product you are viewing is available on this page.
Within the section on this page where you can view and select the size options, there is a link labelled Size Chart that when selected will display a pop-up size chart for the product you're viewing.
We recommend you read the information carefully including the introductory information that may help determine if this is the right product for you.
Please note that there are differences in the size charts for the Classic cut versus the Pro cut given the difference in their intended usage. Close attention should be paid to sizing recommendations when considering the Pro Cut.
You can also view Size Charts for all of our products as well.
What's the difference between the Men's Classic and Pro cuts?
Fitnatic’s CLASSIC Swim Briefs are designed to fit all body types and be super comfortable. They’re made for the beach, by the pool or for under your boardies or footy shorts. They offer a great fit with good coverage, versatility and flexibility.
COMING SOON: Fitnatic’s PRO Swim Briefs are designed specifically for athletes who require greater movement, flexibility, support and performance. The cut sits lower on the waist, is higher around the leg to maximise movement, flexibility and performance and significantly tighter in fit to provide the support a guy needs in all the right places when competing in sports like swimming, diving, water polo, triathlon and other aquatic sports.
Fitnatic’s PRO Swim Briefs are very different in both cut and fit compared to the Fitnatic Classic Swim Briefs. If you prefer the briefer PRO cut but without the tightness of the competitive fit, we recommend you choose a minimum of one size up.
How should I care for my FITNATICS?
