If you want to keep riding year round, consider the LAS Victory Limited helmet, supplied with both winter and summer pads. For hot days, the high-end Italian lid provides excellent ventilation with 25 vents and internal channels, and weighs a feathery 260gm, plus there’s a removable washable one-piece liner/bug net. It’s easy to adjust the fit one-handed, and there’s 59mm of play to secure your size. It’s also supplied with a reflector kit – a nice touch.
