Swingman vs authentic jersey is the first question when you buy an NBA jersey. Nike and Mitchell & Ness use both names but describe them differently, so this page keeps the brands apart and ends with how to pick your size.

Short answer: On Nike's current product pages, Swingman jerseys have a replica design with heat-applied graphics, and Authentic jerseys match what the players wear, with stitched twill details. Mitchell & Ness, which recreates throwback jerseys, says authentic has the tighter athletic fit and swingman a slim but roomier one. Use the size chart of the brand and type you are buying.

What does Nike say about Swingman and Authentic?

Nike has no page that defines the words; its NBA jersey pages only have a Jersey Grade filter with the values Authentic and Swingman. What follows comes from current product pages, which change by season.

  • Swingman: the copy says inspired by what the pros wear, and calls it a replica design. Heat-applied graphics with twill name and number; breathable polyester mesh.
  • Authentic: the copy says it matches what the players wear. Stitched-down twill team and player details (zigzag-stitched, with a heat-applied NBA logo, on one page); lightweight knit with stretch.
  • Fit: the same standard fit line on both pages. Nike does not say there that Authentic fits tighter.

What does Mitchell & Ness say?

Mitchell & Ness recreates past player-worn jerseys. Its Australian store explains its two NBA types:

  • Authentic: an exact, one-to-one recreation of the jersey worn on court, with the same fabric and stitching. Lettering follows the original: screen printed if the original was.
  • Swingman: printed twill names and numbers, and a polyester mesh slightly thicker than the original.
  • Fit: authentic is a tighter athletic fit, slightly shortened versus the court-worn version. Swingman is slim yet roomier, with more room in the shoulders.
  • Label: the jocktag at the hem says Authentic or Swingman.

NBA jersey size chart: how to pick your size

  • Nike: one shared chart, linked as Size Guide on each product page. Measure around the fullest part of your chest with the tape horizontal. If chest and waist differ, order by chest. Between sizes, the smaller is tighter and the larger looser. On the pages we read, Nike does not say its jerseys run true to size. See also our Nike size guide.
  • Mitchell & Ness: separate charts for Authentic and for Swingman / Team Heritage, which it calls a general guide. One Swingman product page says true to size, size up for a more relaxed fit.
  • Our size guide for Mitchell & Ness says: Swingman jerseys fit slim and true to size; for the classic loose look, go one size up. Authentic (Legacy) jerseys run even slimmer, so size up one full size. Open the Mitchell & Ness size guide.
