The well-ventilated Tectal 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 helmet. The reinforced EPS 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.
