Why should underwear fit only by waist size?
Most brands size boxer briefs mainly by waist.
But ride-up and discomfort often start at the thighs — not the waist.
That’s why PREDICTION offers two fit profiles:
- Standard Fit → More relaxed through the thighs
- Slim Fit → More tailored, closer-to-body fit
Choose the fit that matches your body shape for better comfort and reduced ride-up.
Find your preferred fit.
- Standard → relaxed everyday comfort
- Slim → closer, more tailored fit
Thigh under 21"? Slim may fit better.

Find Your Perfect Fit
PREDICTION is built differently.
Waist size isn’t everything — thigh fit matters too.
Relaxed, maximum comfort.
Designed for everyday comfort with a more relaxed feel around the thigh. Best if you prefer more room or have larger thighs.
Closer, tailored fit.
Same waist size, but with a slimmer leg opening for a closer fit. Best if regular boxer briefs feel too loose around your thighs.
Which one should I choose?
Still not sure?
Start with your normal waist size. Then choose the fit that matches your thighs.
