Riddell SpeedFlex vs. VICIS Zero2 – Football Helmet Comparison

Design Philosophy and Construction

The Riddell SpeedFlex is a helmet rooted in traditional football design but updated with modern safety enhancements. It’s recognized for its distinctive front flex panel and a polycarbonate shell that integrates flexibility to absorb impact. In contrast, the VICIS Zero2 is engineered from the ground up as a piece of head protection, not just a helmet. Its unique construction features a deformable outer shell that compresses on impact, much like a car bumper, and layers of internal technology designed to disperse impact energy efficiently.

Impact Protection Technology

Riddell’s approach centers around its Flex System, which builds flexibility into the shell, facemask, and clips to reduce force. It also incorporates Patented Side Impact Protection (PISP) to address hits from the side — a common source of injury. Inside, the Composite Energy Management system ensures padding stays in place and performs consistently during play.

On the other hand, the VICIS Zero2 uses a five-layer protection system that includes a deformable shell, RFLX 2.0 columns, and a Form Liner supported by DLTA pods. These pods both protect and conform to the player’s head, enabling an exceptionally tailored fit. Each layer in the Zero2 is designed to absorb and disperse energy in different ways, making it one of the most sophisticated systems available.

Fit and Comfort

The SpeedFlex uses an inflatable liner system, requiring a special Riddell pump and glycerin-lubricated needle. Once inflated, it offers a snug fit customizable to each player’s head shape. The Cam-Loc chinstrap also makes quick adjustments possible without needing to remove the helmet. However, improper inflation can damage the liner, and such damage voids returns.

VICIS eliminates the need for inflation with its DLTA Fit System. Players can snap in or out pods of varying thickness across six key areas in the helmet. This modular approach makes fitting simpler and more reliable. The Form Liner under the pods further enhances comfort and stability, especially at the back and sides of the head. No tools or air are needed — a significant advantage for ease of use and maintenance.

Vision and Field Awareness

The SpeedFlex offers solid visibility and a lightweight HS4 stainless steel facemask that’s thinner than previous generations. However, the VICIS Zero2 takes visibility a step further, with facemasks designed for optimized vertical and horizontal sightlines, giving players a clearer view of the field and their surroundings — a key benefit for skill positions like quarterbacks and defensive backs.

Weight and Aesthetics

Weighing approximately 3.45 pounds, the SpeedFlex offers a balanced feel and is widely used at the high school and college levels. The VICIS Zero2 is 15% lighter than its predecessor (the Zero1), though depending on size, it may still be slightly heavier than the SpeedFlex. Its sleek, professional design is noticeably more modern and minimalistic, which many players find appealing.

Chinstrap and Facemask Compatibility

The SpeedFlex comes with a white soft cup Cam-Loc chinstrap, with upgrade options for hard cup or TCP designs. Facemasks are not included but are widely available and easily swappable thanks to the quick-release system. The Zero2 includes a SportStar Extra Deep Hard Cup chinstrap (black or white, depending on availability) and one stainless steel facemask of your choice, which mounts securely to the helmet.

Safety Ratings and Return Policies

Both helmets boast Virginia Tech’s top 5-star safety rating, with the SpeedFlex making history in 2014 as the first helmet to score under 0.2 in STAR value. VICIS continues that trend with its highly engineered protective layers. However, it's important to note that the SpeedFlex has strict return limitations if the liner is damaged during inflation, while the Zero2 avoids this risk by not using inflatable components.

Which Helmet is Right for You?

If you’re seeking a time-tested, customizable, and widely used helmet, the Riddell SpeedFlex offers excellent protection and flexibility. Its inflatable fit system and facemask options make it adaptable to many player preferences.

If you want cutting-edge technology, a premium fit without inflation, and the most advanced impact absorption system available, the VICIS Zero2 is the superior choice. It’s especially ideal for players who prioritize safety, visibility, and a snug, no-fuss fit.
