The Giro Terra MIPS is an excellent helmet for ladies looking for style, function and protection. Giro's Passive Aggressive Ventilation System has low-profile exterior vents with interior channels inside the liner and padding keeps the proper amount of air moving through the helmet to prevent overheating and keep your temperature regulated on the mountain. The In Form Fit 2 Fit System is very lightweight and discrete that offers up to 6cm of adjustment for a perfect fit. The Terra is fully equipped with MIPS (Multi-Directional Impact Protection System) which uses a low-friction inner liner that rotates independently upon impact to redistribute energy rather than pass it on to your head. If you want a great looking helmet, loaded with comfort and safety options, the Giro Terra MIPS is a perfect option.
