FAQs

Will the helmet fit me?

The helmets are available in one size only and will fit heads between 55cm and 59cm, depending on model, which roughly equates to a standard size ‘Medium’. We would highly recommend measuring your head prior to purchase in order to ensure the sizing is correct.

In order to measure your head you'll need a flexible measuring tape (like a cloth or plastic tape measure). Wrap the tape around your head, positioning it slightly above your eyebrows and ears, and across the back of your head at the point where it naturally curves outward. Ensure the tape is snug but not too tight, note the measurement in centimeters, and compare that to the size range listed on the product pages.

Remember: every head is unique, and a measurement within the range doesn’t always guarantee a perfect fit.

What is the status of my order?

The shipping status of your order can be checked with tracking ID you receive in your shipping confirmation email.

Are the helmets compatible with action camera mounts?

Do not modify, alter or change the helmet, particularly the outer shell of the helmet.  Do not add anything to the outside of the helmet, particularly stickers, decals or adhesives.

Can I order from outside the US?

Yes, from certain countries. We can ship to anywhere that accepts the U.S. CPSC 1203 bicycle helmet safety standard, namely the USA, Canada, China, Taiwan, Japan, and Brazil.

Should I replace my helmet after every impact?

Yes, you should replace your helmet after impact. This is because the helmet is designed to absorb energy through partial destruction of its inner materials, which may no longer offer full protection after a crash.

What do I do if the panels release?

If the helmet was not involved in an accident or damaged by a significant impact, it is possible to reattach the panel using the original Dual Lock connectors. Simply re-position the panel in its original position and use gentle pressure to snap it in place. Please use common sense. If you have any doubts about the condition of your helmet or the RLS panels, it should be replaced.

Is there a crash replacement program?

Unfortunately we are not able to offer a crash replacement program.

How often should a helmet be replaced?

We recommend that you replace a helmet with RLS every 3 years. Damage to the structure of a helmet can be invisible.

What safety standards are your helmets certified to?

Our helmets are certified to U.S. CPSC 1203.

How do I care for my helmet?

Clean with only mild soap and water using a soft cloth. Do not use chemicals, solvents, or heat. Store in a cool, dry place, away from direct sunlight and temperatures above 112°F (50°C)

What is the warranty policy?

All our helmets come with a one year limited warranty. To find out more specifically, please read our terms and conditions.

What is the returns policy?

You can return your unused, unworn helmet within 14 days of receipt for a refund. Helmets must be in their original packaging and not damaged or altered.
