The Tectal is a mountain bike helmet designed by the brand Poc, to accompany you on all your rides and races on trails and paths. This Tectal helmet features large vents offering excellent ventilation, which is particularly useful in hot weather. Additionally, it is equipped with an EPS liner, which is thicker on the most exposed parts of the skull, providing better protection. The unibody shell, meanwhile, works like a monocoque, reinforcing the structure of the helmet while maintaining a relatively low weight. Compared to the Octal helmet, this mountain bike helmet offers more extensive coverage, thus providing greater protection. Finally, the size adjustment system is lightweight and easy to use, for a comfortable and secure fit.
