Marshawn Lynch is making sure you are in "Beast Mode," even in your underwear.

The running back is expanding his lifestyle brand Beastmode, by teaming up with underwear company PSD for a new collection of boxer briefs.

Lynch's designs feature colorful prints and the signature PSD woven waistband. A majority of the new styles are  branded with different takes on the Beastmode logo, but one pair takes cues from the football field with a bright graphic of yard lines. 

The new collection will be available online and at select retailers on October 6.
