1. Are Wonderballs underwear safe for men's health?
Yes! They’re certified OEKO‑TEX® Standard 100, meaning every component (fabric, thread, dye) has been tested and confirmed free from harmful substances
2. Do you use sustainable materials?
Absolutely. We use ultra-soft Pima cotton blended with Lenzing™ fibers, produced with eco‑friendly closed‑loop processes
3. What style options do you offer?
We carry four core styles—briefs, short boxer briefs, long boxer briefs, and sport boxers—each in a range of essential colors
4. I sweat a lot—will they keep me dry?
Pima cotton naturally breathes well. Our sport boxers, with performance design, help manage moisture during activity.
5. How do I find my correct size?
Check our Size Guide under Resources. Log in and review your previous orders there for a smooth experience.
6. Can tight underwear affect fertility?
While snug styles like briefs can raise scrotal temperature, our boxer briefs offer a balance—close to the body, breathable, and supportive
7. What about chafing issues?
Our boxer briefs and sport boxers have a snug-but-not-tight fit and breathable fabric, minimizing friction and irritation.
8. How should I care for my Wonderballs?
Wash in cold or warm water, tumble dry low. Avoid bleach and fabric softener to maintain fabric integrity.
9. Will the colors fade over time?
Not with proper care. Our dyes meet OEKO‑TEX standards, and cold wash helps preserve fade-resistant colors.
