The Well-Ventilated Tectal The POC Tectal MTB Helmet offers more coverage than conventional mountain bike helmets and has a highly efficient ventilation design, optimized and evaluated through wind tunnel testing. The lightweight size adjustment system ensures a comfortable and secure fit. The well-ventilated Tectal has been specifically developed for aggressive trail riding and enduro racing and incorporates the aramid bridges system from POCs proven and award-winning Trabec helmet. The reinforced EPS liner provides a high level of protection and the unibody shell construction, introduced in POCs ground-breaking Octal road cycling helmet, further enhances the safety properties and construction integrity of the helmet while maintaining a low weight. Extended Coverage With extended zones around the back of the head and the temples, the Tectal gives extra coverage where it's really needed.
