The new Altis from the cranium custodians at 100 Percent was engineered for the demands of the modern-day mountain biker, and we find it a really good choice for women due to its comfortable fit (head and ponytail). A lightweight option with 14 ventilation ports for maximum airflow keeps you cool and comfortable; Smartshock technology protects you from rotational impacts and a polycarbonate shell guards against any hits; adjustable visor blocks the sun, ensuring you can grind trails glare free.
