Sizing Information for Giro Helmets:
Mr MacfarlaneExcellent helmet, easy to adjust & plenty of vents to keep you cool. Also comes with handy skull cap for colder days.
Matt CAwesome service and great helmet. Delivered without any faults to Australia. Was recently in a crash and had to buy a new helmet. I was wearing the exact same helmet (ionos) and had minimal injuries even though the helmet took a good hit. 10/10
Mr FriendComfortable and super light. Very good light helmet for racing
NelsonRiderLightweight, well ventilated, fits well (but that's a personal issue) and at a "couldn't refuse" price
Mr EnholmNice fit, airy.
Graham HallBought this to replace my 'ageing' Giro Pneumo. As I removed it from the box the first thing I noticed was the weight or lack of it. This a seriously light helmet. Fits beautifully with the Rocloc 5 system holding the helmet securely. Once riding you hardly notice the helmet. 2 sets of pads and a padded cap to keep your head warm in colder weather complete the package. The best thing about the helmet? Merlins price -
DargieEasy to purchase. Exceptional service from Merlin. Arrive quickly and as ordered. Recommend very highly. The helmet is great!
Mr BirdExcelent helmet very light, good fit and stylish, with lots of ventilation. Merlin as usual coming up trumps with the best price and service.
Mr LyonThis helmet is a great buy. Not only is it made to Giros normally exceptional build quality and full of great design innovations. It also was an amazingly good price and deliver super fast, something that always makes me look to buy from Merlin Cycles before anyway else. I would recommend Giro to anyone what ever your budget, but if your after a pro level road helmet then this is the best one for its price!
Mr StewartVery happy with this purchase - the skull cap has been great during the recent cold spells.
Mr LeitePerfect fit, reasonable weight and amazing ventilation. Super value and highly recommended.
Mr RobsonGreat Helmet, with spare pads and a cold weather pad,
Mr PollicottExcellent helmet. You hardly know you are wearing it. Would recommend the helmet to ahyone.
Jose Carlos Senukproduto top, entrega com rastreamento, sempre compro na Merlin, e continuarei comprando, parab
Miss NaylorThis helmet is of great quality. It is extremely light yet offers excellent protection which Giro is reknown for. A helmet that is priced at the higher end of helmets but worth that extra for its sleek looks.
