Bauer's best selling Elite helmet of all time. The Re-Akt draws from YEARS of research & development and is packed with all kinds of new technology, all with the single purpose of reducing risk for concussions. While no helmet can PREVENT concussions, Bauer`s work here is remarkable and our early testing finds this to be an extremely comfortable helmet. The free-floating `Suspend-Tech` liner and Bauer`s Rotational Force Management work in tandem - when you get hit, the Suspend-Tech liner moves independently from the memory foam liner to help protect the brain from additional movement. This helmet will look very similar to the incredibly popular 4500 line and also offers a quick and super easy tool-free adjustment. Bauer has really stepped up here.
