Liv Hjälm Liv Extima 51-55 cm. Mattvit

Optimized ventilated aerodynamics design. Design minimizes drag, producing maximum speed in real-world rider positions. Strategically placed AeroVent ports optimize airflow through the helmet, which improves aerodynamics and adds head-cooling ventilation. AeroVent ports pull incoming air through the helmet and streams it through deep internal channels to regulate temperatures during hard efforts. TransTextura Plus™ anti-microbial padding helps fight bacteria growth and the natural property of the fabric inhibits microbes that cause odors. Low and high speed impact-tuned construction with optimized low-density EPS, and an ultra-thin toughened polycarbonate shell. Element Strap System (ESS) brings together Cinch Pro™, Optimal Position Y, and LiteForm™ webbing into one fit and retention system for superior fit and comfort right out of the box. Cinch Pro™ fit system offers optimal coverage by cradling the occipital bone for full protection, support and comfort. Lightweight, LiteForm™ webbing wraps around the head better for a more secure fit and is hydrophobic so it won’t absorb sweat or stretch out like other webbing
