Specialized Ambush 2 Helmet Features: Sized to drop in with a highly customisable fit and precision adjustment. The Ambush 2 features Specialized's SBC Integrated Fit system and adjustable Tri-Fix splitters to provide a dialed fit. Fine-tune your vision using the Ambush 2’s Occipital Base Adjustment to precisely adjust how the helmet sits on the brow for seamless integration with goggles and glasses for an unrestricted view down the trail. Innovative sunglasses storage with hidden rubber flaps maintains a secure, rattle-free fit, keeping your glasses safely stored when you need to get them out of the way during long climbs or moments of rest. Computational Fluid Dynamic design integrates the maximum volume of internal channeling for optimal airflow through the helmet, drawing heat away from the head. 4D brow cooling, which provides a gap between the helmet and forehead, draws airflow into internal air channels at every speed.
