What this product does

The Register Mips II delivers everyday performance with a two‑piece in‑mold shell that blends durability and low weight. The Mips® Evolve Core system helps reduce rotational forces during certain impacts, while the Roc Loc® Sport Mips fit system provides one‑handed adjustability with a wide 7 cm range. Large vents and internal channeling pull air across the scalp for impressive cooling, and the removable visor adds flexibility for sun or shade. Its compact shape and lightweight build make it easy to store inside a backpack, gym bag, or pannier when not in use.
