Klim Defender Zip Shirt

The newest addition to KLIM’s Intelligent Base Layer lineup is the Defender ¼ Zip Shirt. Featuring a medium-weight micro-grid polyester blend knit main body material, the Defender Shirt features more warmth than the Aggressor series with low bulk and ultimate freedom of movement. Easily one of the most comfortable multi-use shirts KLIM offers, the Defender ¼ Zip Shirt will soon be seen all over the snow scene.


  • Medium-weight base-layer
  • Highly wicking, quick drying micro grid polyester blend knit main body material
  • Ultra-comfortable 95/5 poly/Spandex blend
  • Athletic contouring fit
  • 4-way stretch comfort
  • Anti-microbial
  • Anti-pilling
  • Flatlock stitching and tagless design for maximum comfort
  • 1/4 length front zipper


We highly recommend finding a cloth tape measure and taking the time to take these measurements.  Klim sizes will not necessarily correlate with fitment in other brands.
