Sizing - Please Note : These Helmets come up on the small side, so if you are in between sizes we would suggest trying a size up. Helmet city are not responsible if the helmet does not fit. MOMO Please do not return anything until we say, as this may prevent us from being able to deal with your request. If you are generally happy with the fit, leave the helmet on for a good length of time to ensure it is not pressing in places that are not immediately apparant. If a helmet is really pressing on your forehead this can sometimes cause a headache over time so it may be worth trying another size or brand. Some Brands have specific Medium sizes, for example Roof, which can give a very accurate fit if you are that size, for example :

A poorly fitting helmet may not only be uncomfortable, more noisy and may move around when riding if too big or give headaches etc if it is too small, it is also dangerous. A helmet simply will not protect or perform as designed if the head inside it is not snuggly fitted against the impact absorbing material inside the shell. complete with ALL tags in place, helmet bag, manual, protective plastic on visor and any other associated parts supplied.Childrens helmets are available in a variety of sizes depending on the Manufacturer, but they are generally : All our Parcels have an Authority to Leave – No Signature Required (ATL) on them and they will be left near your front door if safe to do so. If the driver deems your location unsecure they will leave a calling card.

Our Helmets are sent out in Brand New boxes, items clearly damaged in transit should not be accepted as once signed for, are accepted as delivered complete and undamaged . Helmet City cannot be held responsible for any damage discovered after the item has been signed for. Sizing information is provided by the manufacturer and does not guarantee a perfect fit. Please use the sizes shown as a guide only. Another thing to bear in mind, is that a helmet in say size Medium from one Manufacturer may fit completely differently to a Medium from another Manufacturer. Therefore we would always recommend travelling to a dealer to try a number of different brands to get the perfect fit for your head shape.

Could be worth considering modifying an SPH-4 rather than an HGU/33 - they're MUCH cheaper and FAR easier to source, and my guess is you'd be less concerned about stripping it, filling, sanding, painting, etc. especially if it has a bit of damage.
