JM4540 - Back Nep Ump Shorts - 101 Classic Navy

$ 158.00

Jackman’s heavily textured “Back Nep” fabric feels right at home in a pair of shorts. The dense, crisp weave has a dry hand and structured feel, but it’s still breathable enough for hot weather. Made from undyed organic cotton nep yarns, the threads are left unprocessed before weaving, giving the surface a unique, slubby texture that only gets better with wear. The fit takes inspiration from old umpire pants, with oversized patch pockets that run wide from waist to hip. We were immediately drawn to the hand feel and distinctive silhouette when we first saw this fabric in a coach’s jacket, and these shorts deliver all the same qualities in a warmer-weather package.

  • 100% cotton
  • Organic cotton “Back Nep” fabric with dry, textured hand
  • High-density weave with natural slub character
  • Crisp finish, breathable for warm weather
  • Elastic waistband with internal drawstring
  • Front trouser-style pockets
  • Oversized wraparound back patch pockets
  • Umpire pant-inspired silhouette
  • Made in Japan (Fukui Prefecture)

A variance of .5" is within tolerance. 

Fit Notes: Tommy is wearing a size medium in the shorts. You can get away with multiple sizes in these because of the drawstring. It really just depends on how roomy they like them. We would recommend you snag your true size in these. Tommy is 5'10," 165lbs with a 33-34" waist.
