An integral part of our Atom series, the Proton is a twin tipped diamond shaped kneeboard with a thin profile and a continuous rocker for insane shredding at any ability level. Our cushy orthodic kneepad and flex zone belt strap will keep you in place on the deck and feeling good. For optimal control engage the Dual Option fin system and retract the fins for a looser feel. Getting started is easy with our pop up handle holder.
