If you want a sleek look and the protection you need to really get after it on the mountain, the new Giro Jackson MIPS is the lid for you. 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. A TPU Injected Brim adds a touch of style. Freeriders in search of the perfect helmet with a rad, low-profile can look no further than the Giro Jackson MIPS.
