Martian A1 Modular Full Face Helmet

A helmet only protects you properly when it fits. Take two minutes to measure before you order.

How to measure your head

Use a soft measuring tape. No tape? Use a piece of string, then measure the string with a ruler.
Wrap it around the widest part of your head, about one inch above your eyebrows and just above your ears.
Keep the tape level all the way round and comfortably snug.
Measure two or three times and use the largest reading.

Match your measurement to the chart

Sizing differs between helmet models, so always use the size chart shown on the product page of the helmet you want. Don't assume your size in one helmet is your size in another.

How a helmet should feel

Snug all the way around, with the cheek pads touching your cheeks.
No pressure points or hot spots on your forehead.
With the strap fastened, the helmet should not roll forward off your head or twist freely side to side.
New helmets loosen slightly as the padding beds in, so a firm fit is normal.

Between two sizes?

Email contact@ridercape.com with your measurement and the helmet you're looking at, and we'll help you choose.

Description

The Martian A1 is a modular full face helmet with a flip-up front and a double sun visor system, made for riders who want one lid for commuting and longer trips. It meets D.O.T. safety standards and keeps weight down with a lightweight shell. The quick release buckle and through-flow venting make it easy to live with day to day.

Key features

Meets D.O.T. safety standards: lightweight, high-quality material that is shock resistant and penetration resistant, with a strong cushioning effect.
Flip-up modular design: lift the front when you stop without taking the helmet off.
Double sun visor system: integrated UV, anti-fog lens cuts glare so you can see clearly.
Quick release buckle: adjustable chin strap that is comfortable and easy to open.
Ventilation system: mouth vent eases breathing and works with the rear outlet on the tail to release heat from inside the helmet, so the airflow channel does not clog or run hot.
