The Ally Pro is an incredibly lightweight ski helmet for women who want a low-profile helmet that simply looks good & fits great. This model available in XS. Features Passive-Channel Venting Channels on the inside surface of the EPS direct air-flow between your head & the helmet, removing moisture & excess heat; keeping you dry & comfortable all day long. Available on all K2 helmets. 360 K2 dialed Fit System An evolution of the K2dialed Fit System™, the new 360 K2dialed Fit System™ delivers unparalleled customization. A web design that is integrated into the textile liner provides maximum comfort & a secure fit. Thanks to more evenly distributed pressure, the all-new 360 K2dialed Fit System™ eliminates unwanted pressure points regardless of your head shape. Washable Full Wrap Liner System This full-coverage, washable liner snugly cradles your head, creating the unmatched fit of a K2 helmet. The liner features a crown mesh that wicks moisture & breathes to prevent overheating. The Full-Wrap Liner System is seamlessly integrated with both our standard & 360 K2dialed™ Fit Systems & K2 Baseline Audio, creating the ultimate user experience. There are no gaps, which means a better fit & enhanced comfort. Level 3 Baseline Audio System The K2 Level 3 Baseline Audio system seamlessly connects you with your cell phone or media player. The audio system comes pre-installed in Baseline Audio Earpads. The speaker housing creates a minimal, low-profile stowage so you won’t notice the speakers unless the music is playing. If you would rather ride without the speakers installed, they can be easily removed from the earpads. With a detachable cord & an all-new on-cord audio controller for initiating on-the-go pause/play & answer/hang-up functions, your media device is literally at your fingertips. In-Mold Construction In-Mold is the premium construction for ultra-lightweight performance helmets & is characterized by an EPS liner that is molded directly to a lightweight polycarbonate shell. The result is a construction so light you’ll forget it is even there.
