How to Fit Your Helmet Correctly
Step 1: Measurement
Place a tape measure slightly above the ear and bring it across the mid forehead completely circling the head about 1 inch above the eyebrows.
Do this 2 or 3 times to double check that you have the largest measurement. If you do not have a tape measure, use string and then a rule to measure the string.
With your largest measurement compare it to the size chart above for Street, Snow and Water. Also see the Q&A about fittings below.
Step 2: Wearing the helmet or trying on
If you're in the store and you've determined your size in Step 1, try it on and adjust the straps. Now ensure the helmet sits level on the head and does not slide or move freely when you move your head side-to-side. If it moves, the helmet is too large. Change out the default internal foam pads (8mm) to a thicker set (12 or 16 mm) to provide a snug fit. Combining different pads will further customise your fit (e.g. 12 mm at the front and 8 mm at the rear). The foam pads attach by velcro.
Test it side-to-side again and do the push test: When someone places a palm to your forehead they should not be able to push the helmet backwards off your head.
If changing to thicker pads still does not help, you may need to try one size smaller. Once again adjust straps and internal foam pads for fit and do the same test side-to-side roll and push test.
Important: Do not allow a toddler or child to ride without making these strap and foam adjustments. For Little Nutty, ensure the Spin Dial adjustment is also made.
Step 3: Proper fit
The front of the helmet must sit above the brow and the back of the helmet must not touch the nape of your neck. The chin strap should be snug but not too tight as to cause discomfort or choking. Securely fasten the chin strap and try to roll the helmet off your head. If the skin on your forehead moves slightly, you have a good fit.
The side straps should be adjusted to form a clean triangle encompassing each ear area.

Q. Will the Little Nutty or Baby Nutty helmet fit my child?
A. The Baby Nutty is designed for ages between 12 and 36 months. The Little Nutty (Toddler) is for toddlers aged approximately 3-5 years with a head circumference measuring 46cm - 52cm. It can be adjusted with a Spin Dial. We do not recommend any helmet for a child aged 1 year old or less. A child must develop neck strength in order to have optimal benefit from a helmet.
Always measure your child's head circumference and refer to the helmet size chart on this page. Or, ideally, fit the helmet at our store or another Nutcase dealer. All kids are different, but in general those over the age of about 6 are better suited to the size range of the S-M helmet.
Q. I'm an adult but I'm in-between the two size ranges for your helmets, what should I do?
Our Street Helmets are S (52-56cm), Medium (56-60cm) and Large (60-64cm). If you are right on the range between two sizes, you should generally choose the larger helmet. You can then use the included pads to give you a snug fit and the extra width and depth will better cope hair and better cover your frontal lobe and temples.
When you receive your helmet always remove the default padding from inside the helmet and use the foam pads in the box to create a custom fit at the back and front of your head.
- Do not use commercial or domestic cleaning products on your helmet. Rinse the helmet in clean water and use a small amount of PH neutral soap/detergent only.
- Dry off or leave to dry away from direct heat or sun.
- Always store helmets in a dry, cool, dark and chemically-neutral place. Avoid UV rays, sharp corners, sources of humidity. heat or corrosive substances. Do not store when wet.
- Replace the soft foam pads when required.
Always store helmets in a dry, cool, dark and chemically-neutral place. Avoid UV rays, sharp corners, sources of humidity. heat or corrosive substances. Do not store when wet. Do not leave outside even if your shed, deck, car port is covered. Do not leave inside cars, boats or other vehicles as warm temperatures are concentrated in these areas.
