Weighing in at 235 grams, the G1 MIPS is the lightest helmet we have ever made. It is the climbers' favorite on the ProTour. Not only is it a featherweight, but it's extremely well ventilated. Twenty-two vents and internal air channels create 8% more airflow over the head than wearing no helmet at all. It's also comfortable--vital for long days in the saddle. The Super Lightweight ARS Fit System ensures a snug and comfortable fit with no pressure points. The head basket is adjustable. Two sets of pads are included so you can choose between superlight and comfort pads. Awarded the esteemed Virginia Tech 5-Star "Best Available" protection rating, you can trust that the G1 MIPS is a great choice. The MIPS system helps reduce the risk of rotational injury. When you're after every bit of speed, the addition of the Aeroshell (sold separately) transforms the G1 MIPS into an aero helmet. - Lightweight - Well ventilated (22 vents) - Advanced Rollsys system - Comes with race and comfort pads - Lazer Aeroshell compatible (sold separately) - UCI World Tour helmet - MIPS layer - Construction: In-Mold, EPS foam, polycarbonate, nylon - Weight: 235g - Certification: CPSC
