Linemen experience more than twice as many impacts as other players, with the largest percentage of hits to the front of the helmet.¹ The majority of those impacts are low velocity between 2.1 and 4.5 m/s.² Based on this data, the TRENCH helmet was designed with additional offset in the frontal region, specifically tuned for low velocity impacts. To complete this optimization, VICIS leveraged the combination of a deformable outer shell and engineered impact structure.
Using the industry standard linear impact ram and testing protocols, independent testing was completed at the front and oblique front locations, focusing on reducing acceleration at low velocity (3m/s) impacts.
The VICIS TRENCH uses the ZERO2 as its base, which has been designed from the ground up for 2021. Guided by the latest helmet testing protocols, the base ZERO2 was optimized for the complete range of impacts, low to high velocity.
*Testing was performed on a single sample helmet of each type at an independent testing laboratory. Testing was completed using a pneumatic ram impactor as used during the NFL/NFLPA helmet testing protocol. The helmets were impacted twice in each location at 3 m/s and an average peak acceleration is recorded.
