The smooth silhouette features the adjustability of an In Form fit system so you can dial in your perfect fit, even with gloves on, while Thermostat Control adjustable venting allows you to let out hot air if you need to. If you want to rock out while on the mountain, you can insert the audio systems by Outdoor Tech (sold separately) inside the earflaps and glide to your favorite tunes. The Ceva Mips® is also equipped with the Multi-Directional Impact Protection System (Mips®), which can provide more protection in certain impacts.
