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
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
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.
Good helmet and value for money. Good field of vision. A bit on the heavy side, but it is a large adventure helmet and is a comfortable fit and the integral sun visor a must.
