Product description
The Source MIPS helmet combines technological maturity and superior safety with the design of a modern trail helmet.
Ventilation through 17 vents, supported by internal channels, can keep your head at the right operating temperature even in the middle of summer. Comfortable fit on the head is ensured by the Roc Loc 5 clamping system, into which
is an integrated MIPS liner. The label is adjustable, secured with screws. Resistance to
everyday scratches are guaranteed by the polycarbonate that covers the shell from below. Extended back protection is already a matter of course.
MIPS (Multi-Directional Impact Protection System) provides enhanced protection against
rotational forces on the head. More atMIPSprilby.cz">www.MIPSprilby.cz

Technology
-
ROC LOC® AIR A revolutionary clamping system that improves both fit and ventilation of the helmet. The clamping system creates a small space between the head and the helmet itself where cool air flows. The setting options are the same as for the Roc Loc® 5 system.
-
IN-MOLD® Designation of a technological process in which EPS polystyrene foam is pressure-injected into the shell and reinforcements enclosed in the mould. Their connection reinforces the area of the vents and ribs. The result is a compact, uniform, lightweight, safe and very durable helmet.
-
MIPS (Multidirectional Impact Protection System) is a slippery insert between the EPS shell (helmet body) and the inner liners. In the event of an angled impact (for example, if you catch your head on a branch), the helmet's EPS shell will roll a few millimeters over the MIPS layer, protecting your head and brain from the violent rotational jerk.
-
The SUPER FIT™ System is made up of up to four helmet sizes designed to cover a range of different head sizes for all users. Thanks to this system, the helmets of the higher categories are ideally prepared for every rider.
