Question 1

Can I wear this helmet in the rain?

Accepted Answer

Yes, the helmet is safe to use in rain. The MIPS liner and EPS foam are not affected by moisture. However, the pads can become wet and might require drying. No integrated electronics.

Question 2

What is the actual weight of the small/medium size?

Accepted Answer

The S/M weighs approximately 280 grams according to our own measurement (and consistent with user reports). The official spec is around 275g, but it varies slightly by finish.

Question 3

What is the difference between this and the Giro Register MIPS (non-II)?

Accepted Answer

The II version has updated padding for better moisture management, a slightly refined shape for ponytail compatibility, and a new color palette. Safety and MIPS system are identical.

Question 4

Can I wash the entire helmet in soapy water?

Accepted Answer

Only the removable pads should be washed (hand-wash, air dry). The shell can be wiped with a damp cloth. Submerging the entire helmet could damage the EPS foam and MIPS liner.

Question 5

Is the visor adjustable?

Accepted Answer

Yes, the visor can be tilted upward slightly, but it is not fully removable. It provides enough sun coverage without obstructing vision.

Question 6

Does it work with a GoPro or headlight mount?

Accepted Answer

There is no dedicated mount, but adhesive or strap mounts can be attached to the smooth top shell. Avoid blocking the front vents. Some users recommend Giro's optional accessory mount (sold separately).

Question 7

Is this helmet certified for e-bike use?

Accepted Answer

The Giro Register MIPS II is CPSC certified for bicycle use, which covers most pedal-assist e-bikes under 20 mph. For higher-speed e-bikes, consider helmets with additional certifications like NTA-8776.

Question 8

How does the sizing run compared to other Giro helmets?

Accepted Answer

It runs true to Giro standard sizes. If you wear a medium in Giro Syntax or Savant, the same size in Register MIPS II should fit. Measure your head circumference to be sure.
