No doubt you\'re already familiar with the Lifer Helmet brought to you by S1 and now they\'ve taken their product development one step further and listened to the battle cries of skaters from all disciplines across the globe and are bringing to you the S1 Lifer Helmet including Visor! Building on the success of the standard Lifer Helmet, S1 wanted to give their Lifer Helmet including Visor the versatility to be used with or without the visor at the whim of the skater thanks to the in-mold mounting hardware. The optically correct lens of the visor has been created from a high quality, polycarbonate compound to prevent against shattering and has been given an anti-scratch coating outside to help against minor scratches and scuffs. The inside visor of the S1 Visor Helmet has also been treated to help against fogging when you\'re battling it out on the track.
