This is an authentic Nike NFL game jersey for the Oakland Raiders, featuring player Khalil Mack's number 94 and name 'NASSIB' (note: likely a misprint or custom variant—Mack wore #52; #94 was worn by Khalil Mack’s teammate Bruce Irvin or later by Clelin Ferrell, but 'NASSIB' corresponds to former Raiders QB Matt Nassib, who never wore #94; this appears to be a fan-made or replica jersey with incorrect attribution). The jersey is constructed from lightweight, breathable Dri-FIT polyester with screen-printed silver-gray numerals and lettering. Front displays large #94 centered below the NFL shield logo; back features 'NASSIB' above #94 in bold block font. Short sleeves include partial sleeve numbers (4 on left, 9 on right), and a Nike Swoosh appears on the right chest and left sleeve. Tagged with official NFL and Nike licensing labels at hem and side seam. Designed for on-field performance and fan wear, it offers a tailored athletic fit with reinforced stitching at stress points. Ideal for game days, tailgating, or casual streetwear styling—pairs well with joggers, shorts, or layered under a bomber jacket. While not an official team-issued garment due to name/number mismatch, it follows authentic NFL jersey construction standards and visual language.
