Stay Cool During Every Ride
Threo cycling cap keeps your head dry and fresh throughout journeys. Airy mesh and soft cotton stop sweat from building up quickly. Flexible fit stays snug without causing pressure or marks.

Mesh allows steady airflow so you never feel stifled. Moisture evaporates fast, keeping you comfortable no matter the weather.


Sun And Insect Protection
Smart brim design blocks sunlight and prevents bugs from entering. You stay focused while your skin remains protected on every outing.

Didn’t think I’d like wearing something extra under my helmet, but this is super comfy. No bother with bugs or sun, plus my head doesn’t get itchy either!

My favorite thing is that my head feels dry even after long rides. Easy to wash and still holds up strong—pretty sure it’s durable too.

Love how it sits under my helmet and doesn’t leave lines on my forehead. Air flows well, and I don’t feel sweaty anymore when I bike to work.

Tried the cap because my helmet always gets gross after biking. Big difference! The cap dries quickly and never makes my scalp feel hot or trapped.
