Who is Frosten For?

Frosten is for men like me men who want to feel comfortable, confident, and in control again.

It’s for the guys who deal with sweating or small leaks and never talk about it.

For the men who are constantly adjusting their boxers, checking themselves at the gym, or worrying about staying dry during long days.

It’s for the men who work hard, move a lot, travel often, and don’t want to think about their underwear failing them.

It’s for the men who want something better than the thin, cheap, “performance” boxers big brands keep selling.

Frosten is for:

✔ Men who want real protection without the embarrassment

✔ Men who want to stay dry and comfortable all day

✔ Men who want underwear they can trust in any situation

✔ Men who just want to feel normal again

I built Frosten because I needed a solution for myself and I realized millions of other men needed it too.

If you’re looking for underwear that actually works…

Frosten is for you.

FluidGuard™ Technology

FluidGuard™ is engineered using a three-phase moisture control system designed for high-performance wear:

1. Hydro-Absorbent Intake Layer
Utilizes capillary action to draw moisture away from the skin within milliseconds, reducing surface dampness and preventing irritation.

2. FluidLock™ Micro-Barrier Core
A dense, multi-filament membrane that captures liquid and distributes it evenly, preventing saturation points and eliminating leak-through under high-pressure conditions (gym, sitting, bending).

3. DryShield™ Evaporation Mesh
A breathable outer textile that accelerates moisture evaporation while maintaining a dry, cool surface temperature against the skin.

Combined, this system keeps the garment dry up to 3× longer than standard cotton, maintains airflow, and stabilizes temperature for all-day comfort.
