Sixsixone helmets come with Boa micro adjustment letting you get the perfect fit for comfort and safety on the trails. A padded inner surface and multiple vents also improved your comfort while riding. The best 661 MTB helmets are fitted with MIPS technology. MIPS reduces impact and rotational forces to limit damage to your brain in an accident caused by rotational forces. Extended rear coverage also helps to reduce damage.
