Microsoft is working with sports companies Riddell and Bauer for limited-edition gear inspired by Halo Infinite. Starting with Riddell, the company created a limited-edition football helmet inspired by Master Chief's green and gold Mjolnir armor.

The helmet costs $1000, and it's for display use only--Riddell does not recommend actually using it to play football. Each was hand-drawn using a "multi-step painting technique," the company said.

Master Chief's 117 number is printed on the sides, while there is a 20-year anniversary decal on the back. "Additional upgrades include a special SpeedFlex face mask SF-2EG-TX, a convert-to-black kit that includes black parts, face mask clips, front and back bumpers, custom painted strap-locs and valve caps, and a black hard cup chin strap. The look is completed with an Oakley Pro Shield in Prizm 24k Iridium that closely mimics the visor on Master Chief's helmet," Riddell said.
