Fit & Comfort
No. Our precise cut and unique Slim and Standard fit options prevent thigh roll-up and maintain a clean silhouette throughout the day.
Many boxer briefs roll up because of outdated designs. We offer two thigh fit options for different leg openings, “STANDARD” and “SLIM", so you can choose the best fit for your body type.
We didn’t use uncomfortable silicone grips, just a smarter design that stays in place.
Yes. The seamless waistband stays flat and secure without digging into the skin or leaving marks.
Absolutely. We use premium modal fabric known for its softness, breathability, and moisture-wicking performance, and resistant to odor..
While still breathable like cotton, modal has a higher water absorption capacity, approximately 50% more than cotton, making it particularly suitable for hot summer days and can be beneficial in sweaty situations.
Designed for both comfort and durability, it’s perfect for everyday wear.
Not at all. The pockets are positioned and bonded to balance weight evenly, minimizing movement and discomfort during wear.
PREDICTION underwear features strategically placed pockets that allow you to carry small essentials securely and comfortably. The pockets are discreet, non-bulky, and easy to access when needed. We also designed them with a secured lip opening to prevent items from slipping out even without zipper.
No, unlike cotton, our modal fabric retains its shape well, even after multiple washes.
Sizing & Options
We currently offer sizes from Medium to XL across all collections, with both Slim and Standard fit options.
Check below available sizes…
- Medium / Large / X-Large (Standard Fit)
- Medium Slim / Large Slim (Slim Fit: same waist but slimmer leg opening)
Check our size guide on each product page. If your mid-thigh is around 21 inches, choose Standard for comfort or Slim for a closer fit.
Please refer to our sizing chart for general measurements. If you still need assistance, feel free to email us at info@prediction413.com for further help.
* Standard Fit
If you have no issues of leg rolling up with other brands, then our Standard Fit will fit you prefect!
* Slim Fit
Slim Fit offers the same waste size with Standard Fit but narrower, slimmer leg opening. If you have thinner thighs and have issues with other brands’ underwear being too big around the leg opening and the legs rolling up, we recommend trying our Slim-Fit.
We hope this 2 options give you a tailored fit you will absolutely love!
* Still confused? This is just a guide.
These numbers may not be exact, but we have come up with these numbers after hundreds of tests. Measure your thigh circumference from the crotch. If the number is less than 21 inches, we recommend our slim fit. If the number is greater than 21 inches, standard fit is the choice. We believe these measurements are correct, but they are only examples and everyone feels differently, so use these numbers as a guide only.
