The Jacksonville Jaguars unveiled another twist to their uniform catalog Thursday morning, revealing white alternate helmets.

The all-matte white helmet will debut in Week 10, a home matchup against the Minnesota Vikings at EverBank Stadium. “Shell White” features a matte white finish, black facemask and the Jaguars current logo.

The helmet will be paired with black jerseys.

The announcement was made on social media Thursday morning, the second day of training camp. The team teased the alternate helmets the night before on social media at 9:04 p.m., a hat tip to Duval County's area code.

The social media post listed three reasons for the choice in colors:

All things Jaguars: Latest Jacksonville Jaguars news, schedule, roster, stats, injury updates and more.

The Beach: "Our beaches, adorned with shells, symbolize shared adventure and teamwork. As locals and visitors explore our coastal landscape, these shells remind us of the unity that enriches our experience in Duval and its surrounding counties.

The Military: "Each shell embodies the courage and sacrifice of our military personnel. Like the protective armor worn in battle, shells symbolize the unwavering dedication of our armed forces."

The Game: "Shells, reminiscent of the gear worn by players, symbolize our team's resilience and unwavering spirit. Just as shells protect and endure, our team stands strong and united, facing every challenge with determination."

This will be the first alternate helmet ever worn by the Jaguars.

The reveal comes just a week after the team announced the "Prowler Throwbacks," a uniform combo based on the team's original 1995 expansion uniforms featuring teal tops, white bottoms and a helmet based on the team's original logo on the side of the helmet used from 1995 until 2013.

The all-white helmet has become popular alternative headwear in the NFL over the last few years.

In 2022, the NFL changed its uniform policy to allow a second helmet shell color. The league requires teams to sport the alternate color helmet with a specific optional uniform. The league does not allow for the alternate helmets to be mixed and matched with primary uniforms, and they cannot be mixed and matched with another optional uniform.

The Jaguars are not alone in having white alternate helmets. The Bengals introduced theirs in 2022, the Cleveland Browns and Denver Broncos did so in 2023, while the Minnesota Vikings unveiled white helmets alongside their 'Winter Warrior' uniforms in June.

NFL teams with alternate helmet designs

The Jaguars are certainly not the first team to introduce white helmets, nor are they the first to introduce an alternate helmet design in recent years.

Quickly after the league updated its uniform policy in 2022, 13 teams took advantage of the rule, including the Chicago Bears, Cincinnati Bengals, Arizona Cardinals, Washington Commanders, Dallas Cowboys, Philadelphia Eagles, Atlanta Falcons, New York Giants, New York Jets, Carolina Panthers, New England Patriots, New Orleans Saints and Houston Texans.

In 2023, the Browns, Lions and Broncos introduced their alternate helmets.

A slew of teams are doing so again in 2024, including the Jaguars as the latest fashion trend for the league.
