Funny Cycling Cap - Polyester Under-Helmet Skull Cap - Breathable

Our review of the Funny Cycling Cap finds it best suited for cyclists who want a lightweight, comfortable under-helmet liner that controls sweat and shields from wind and light rain. The single biggest reason to buy is the combination of soft polyester mesh and a built-in visor that keeps sweat out of the eyes while fitting under most helmets; the cap is sold as one size with an elastic band to fit head circumferences of 56-61 cm. This is a practical, lowmaintenance accessory for daily riders and commuters who value comfort and neat hair after a ride.

Key Features

• One size fit: The elastic band on the back accommodates head circumferences of 56-61 cm so the cap fits most adults without pressure points.
• Breathable polyester: Lightweight, soft mesh fabric wicks sweat and dries quickly to reduce dampness under a helmet during long rides.
• Under-helmet design: Thin construction allows the cap to sit comfortably beneath most helmets while preventing wind and dust from reaching the face.
• Sun and sweat visor: A short brim keeps sweat and glare out of the eyes and helps block light rain when riding.
• Durable and wear resistant: Quality polyester construction stands up to regular use and machine washing without losing shape.
• One-year satisfaction guarantee: The brand offers a replacement or refund within one year, which simplifies trying the cap risk free.

Who It's For

The Funny Cycling Cap is aimed at commuters, recreational road cyclists and mountain bikers who wear helmets regularly and want a thin, breathable liner to manage sweat and keep hair tidy. Riders who dislike bulky liners will appreciate the slim fit and short visor that still provides practical protection from sweat, sun and light drizzle.

It is less appropriate for cyclists needing heavy insulation in very cold conditions or for those who want a fully waterproof cap for extended rain; the polyester mesh emphasizes breathability over insulation or full weatherproofing.

Frequently Asked Questions

Will this cap fit under my road helmet?
Yes. The cap is thin and designed to sit under helmets and the elastic back helps it conform to most adult helmet fits.

Is the material waterproof?
No. The polyester mesh is breathable and wicks sweat but is not fully waterproof; it is best for light rain and sweat control rather than heavy downpours.

How do I get a refund if it does not fit?
The brand offers a one-year replacement or refund policy; contact customer support for instructions on returns or replacements.
