Britax Marathon 70-G3 in Chilli Pepper

SafeCell™ Technology features SafeCells designed to compress in a crash, significantly lowering the center of gravity and counteracting the forward rotation of the child seat which normally propels the child toward the front seat
Integrated Steel Bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash
Energy-Absorbing Versa-Tether® features a staged-release tether webbing to slow the forward movement, reducing the crash forces reaching the child, and a two-point attachment to minimize forward rotation while anchoring the top of the child seat

Side Impact Protection comprised of deep side walls lined with energy-absorbing EPP foam distributes crash forces, shields from vehicle intrusion, and contains the head, neck and body
Tangle-Free, Five-Point Harness distributes crash forces across the strongest parts of the body and provides a secure fit
Harness Ultra Guard System (HUGS™) provides resistance to forward movement in the event of a crash
