Liv Infinita SX MIPS Helmets

Sizing Below.  Medium Fits about 70% of women. 


Now that we have MIPS protection, it’s hard to remember a time when this level of helmet technology didn’t exist. Extra brain protection is simply a no brainer, so along with MIPS we’ve added a lower rear coverage design to shield more of the back of the head. Infinita SX is safe, but it’s also styling with all the latest features like the infinitely adjustable and removable moto-style visor, an integrated goggle strap to keep your eyewear steady on descents, and GoPro mounts on the front and top. Whether you’re slowly cruising or quickly charging, the Direct Flow Cooling channels are specially designed to pull in air at both high and low speeds to cool your head. Combining CINCH One Pro with a full 360° belt allows you the snug sizing and height adjustment to create your perfect fit. Cozy, featherweight LiteForm™ webbing also adds head-hugging comfort that allows your head to move naturally while it is protected.
