Here's what other sites are saying:
The K2 Women's Ally Audio Helmet features a super, lightweight design that won't give you a giant balloon-head complex. Equipped with a level 3 baseline audio system, the Ally brings your tunes to your ears and connectivity to your phone while you ride the lift or race down fresh groomers. Its speaker housing has a low-profile, minimal design so you won't even know it's there, and the Ally provides a detachable cord and a single squeeze button for pause/play and answer/hang-up so you don't need to worry about compatibility or buying a separate accessory for your MP3 player or phone. In case the safety bar on the lift accidentally clanks down on your noggin before you're ready to pull it down, the Ally protects your head so you don't have to deal with a splitting headache. Its in-mold construction keeps overall weight down while providing effective protection from sudden crashes on the slopes or from low-hanging tree branches. K2 also equipped the Ally with passive channel ventilation that features channels on the inside surface of the EPS core to direct airflow between your head and the helmet. And you can banish gaper-gap worries, since the Ally comes with a 360 K2dialed fit system that features an ergonomically inspired three-point adjustable interface to maximize fit and customization with the twist of a dial for superb convenience on the fly. The cozy full-wrap liner system easily removes for washing, wicks moisture away, and supplies breathable comfort when you navigate down steep, techy terrain.
Hit the slopes in the K2 Ally Snow helmet-not only does it look great, but it's lightweight and warm.
