The well-ventilated Tectal bike helmet has been specifically developed for aggressive trail riding and enduro racing and incorporates the aramid bridges system from POC’s proven and award-winning Trabec cycling helmet. The reinforced EPS (Expanded Polystyrene) liner provides a high level of protection and the unibody shell construction, introduced in POC’s ground-breaking Octal road cycling helmet, further enhances the safety properties and construction integrity of the helmet while maintaining a low weight. Tectal 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.
