Helmet looks great & fits well but seems a tad smaller than other helmets I’ve had. Sun visor doesn’t operate as smoothly as other helmets I’ve had either

Good value for money, could do more ventilation, the anti fog insert is essential! Comfortable and a good fit!
Nice helmet. Love the colour and built in sun visor, this is the new model has the cut outs for speakers. Wanted a cheap helmet for day to day use. It comes up small. Slight creaking above 55/60mph. Doesn't like side winds. I would buy again, bargain at £117.00!
Great helmet. Light weight
Little loud for my taste.
Comfortable, plenty of vents, main visor comes off really easily if you want to use mx goggle, looks really good too
Nice and comfy. True to measurements. The helmet feels sort of flimsy but it's due to it being so light weight.
Very good looking helmet
