Carerra introduces an expanding and contracting helmet that has an elastic fitting system that molds to the rider’s head.
Instead of finding bike helmets of different sizes, this expanding and contracting helmet from Carrera has an elastic fitting system that molds to the rider’s head, making it a perfect fit. Bless This Stuff reports that the foldable helmet design is inspired by the old leather pistard helmet and it features a flexible frame for improved comfort.
The helmet has rigid lateral segments and adjustable straps that lock into place so its fits snugly on your head. When you take it off, you can press the helmet together so it shrinks and takes up less space in your bag than a standard helmet.
