Bicycle helmets have been made the same way for over 30 years: Expanded polystyrene (EPS) with a polyester shell bonded onto the outside. New MIPS liners are a great innovation that addresses oblique impacts better, but the bicycle helmet has been largely unchanged.
The WaveCel helmet design from Bontrager uses a completely different material called cellular copolymer. When used in conjunction with EPS and a polyester shell, this new material provides a much better management of real-world impacts that might cause a concussion. Even oblique impacts are absorbed much more effectively by the WaveCel honeycomb material by shearing progressively in the event of a hard impact. WaveCel material was developed as a helmet material from the beginning in Portland, Oregon at Legacy Biomechanics Laboatory. Using EPS and a polyester shell for the helmet's exterior allowed the designers at Trek and Bontrager to build the outside of the XXX helmet with familiar materials. Improved airflow ventilation and innovative external styling was always part of the plan when starting with a fresh helmet design.
The Bontrager XXX helmet is a no-compromise aero road helmet with sleek styling and excellent ventilation. The Trek-Segafredo pro cycling team has been putting the new helmet through the wringer of the pro racing season, trusting it to protect them while racing in conditions fair and foul. A Boa closure at the rear of the helmet allows one-hand adjustment while keeping the interior fit system light. The interior also features AgIon padding that eliminates odors naturally. There's even a second interior pad set with a NoSweat silicone channel to help keep sweat out of the rider's eyes. 9 large exterior vents allow smooth airflow when riding in hot and humid conditions.
The WaveCel material does not allow the Bontrager XXX helmet to sustain repeated hard impacts. If your helmet is damaged in a crash, replace it. Bontrager's Crash Replacement Guarantee provides a free helmet replacement if involved in a crash within the first year of ownership
The most comfortable helmet is one you forget about. You want to enjoy the ride, not think about a heavy, poorly-fitting head-bucket, right? That's where Bontrager's Solstice MIPS comes in! Bontrager has a better approach to sport/recreational helmets with two sizes instead of just one. There's a little overlap between the two sizes, but that's to help you if you might wear a cap or hat underneath in chillier temperatures. The MIPS liner (short for Multidirectional Impact Protection System) allows the helmet to reduce the effects of oblique impacts better. A one-handed adjuster knob at the back sets the Micro-Manager II fit system in flash. LockDown strap dividers give the Solstice a comfortable feel on your cheek, while the interior helmet pads are removeable and washable. Big vents and a visor keep you cool and comfortable for the road ahead.
