A word from a dermatologist
Synthetic fabrics like polyester and nylon are less absorbent and trap moisture against skin, which creates a warm, damp environment that can encourage bacterial and fungal growth (e.g., contributing to conditions like intertrigo or fungal infections in skin folds).
I recommend bamboo fiber underwear if you're prone to irritation, precisely because they address the moisture/airflow/friction factors.

The problem
Synthetic underwear made from material like polyester are made from petroleum, they're non-breathable and trap heat.
The microplastics they release are part of the reason testosterone levels have lowered by 50% in the past 30 years.
They also cause irritations for sensitive skins, trap odors and don't last really long.

Bamboo breathes. Its naturally hollow fiber structure moves air instead of trapping it — so things stay cooler and drier down there, not sweaty and suffocated.
Bamboo doesn't cling. No synthetic heat pocket. No damp, stuck-to-you feeling by 3pm.
Bamboo is naturally antimicrobial. Less moisture, less bacteria, less of that end-of-day funk synthetic fabric holds onto.

FAQ
What are the FrontalWear underwear made of?
What are the FrontalWear underwear made of?
95% bamboo viscose, 5% elastane. The bamboo viscose gives you a soft, breathable feel and natural moisture-wicking, while the small amount of elastane adds stretch so the fit moves with you without losing shape. No synthetic, no harmful chemicals.
How does the moisture-wicking work?
How does the moisture-wicking work?
Bamboo viscose fiber is naturally more absorbent than cotton. It pulls sweat and moisture away from your skin and lets it evaporate faster, instead of trapping it against you. That's what keeps you feeling dry through a workday, workout, or commute.
Will these help with chafing?
Will these help with chafing?
The seamless construction plus bamboo's naturally smooth, rounded fiber (unlike rougher cotton fibers) is specifically designed to reduce the friction that causes chafing. If chafing has been a recurring issue for you with cotton or synthetic underwear, this is one of the biggest reasons customers switch.
Are they good for sensitive skin?
Are they good for sensitive skin?
Bamboo viscose is naturally soft and free of the harsher synthetic fibers found in polyester-blend underwear, which makes it a gentler option for skin that reacts easily. Combined with the tagless, seamless design, there's less overall irritation from stitching, tags, or rough fabric edges.
How do I find my size?
How do I find my size?
Measure your natural waist (not your pants size) — wrap a tape measure around your midsection at the belly button, snug but not tight, and match it to our size chart. If you're between sizes, we recommend sizing up for a more relaxed fit.
